2-The chemical structure and unique properties of isopropyliimidazole

2-isopropylimidazole (2-IPMI) is an organic compound with a unique molecular structure and its chemical formula is C6H10N2. The compound consists of an imidazole ring and an isopropyl side chain, where the nitrogen atoms on the imidazole ring are highly alkaline and hydrophilic, while the isopropyl side chain imidizes the molecule with certain hydrophobicity and flexibility . This special molecular structure allows 2-IPMI to show excellent performance in a variety of application scenarios.

First, 2-IPMI has extremely high chemical stability. The presence of imidazole ring enables the compound to maintain stable chemical properties under extreme environments such as high temperature and high pressure, and is not prone to decomposition or reaction. This characteristic makes 2-IPMI perform well in high temperature release process, and can withstand high temperatures without losing lubricating performance, which is suitable for mold release requirements of various complex molds.

Secondly, 2-IPMI has good lubricating performance. The nitrogen atoms on the imidazole ring can form a weak bond to the metal surface, thereby forming a uniform lubricating film on the surface of the mold. This lubricating film can not only effectively reduce the friction coefficient and reduce mold wear, but also significantly improve mold release efficiency, shorten the production cycle. In addition, the lubricating film of 2-IPMI has a self-healing function.

Next, we will discuss in detail the specific research and development process and technical route of mold release agents based on 2-IPMI.

Research and development process of mold release agent based on 2-isopropylimidazole

Developing an environmentally friendly mold release agent based on 2-isopropylimidazole (2-IPMI) is not achieved overnight, but has gone through multiple stages of research and optimization. The entire R&D process can be divided into the following key steps: raw material selection, formula design, laboratory testing, small-scale trial production and large-scale industrial production. Each stage is crucial to ensure that the final product not only has excellent performance, but also meets market demand and environmental protection requirements.

1. Raw material selection

In the early stages of R&D, it is crucial to choose the right raw materials. As the core component, 2-isopropylimidazole, its purity and quality directly affect the performance of the final product. Therefore, we chose high-purity 2-IPMI as the base material to ensure that it can fully play its role in the mold release process. In addition to 2-IPMI, some auxiliary ingredients need to be added, such as surfactants, thickeners, antioxidants, etc., to enhance the overall performance of the product. The selection of these auxiliary ingredients must comply with environmental standards to avoid the introduction of harmful substances.

In order to ensure the quality and supply stability of raw materials, we have established long-term cooperative relationships with many well-known suppliers, conducting raw material testing regularly to ensure that each batch of raw materials meets strict standards. In addition, we are also actively paying attention to new research results at home and abroad, timely introducing new materials and technologies, continuously optimizing raw material formulas, and enhancing the competitiveness of products.

2. Formula design

Formula design is one of the challenging links in the R&D process. A good formula not only ensures the mold release effect of the product, but also takes into account environmental protection, economicality andEase of use. To this end, we have formed an interdisciplinary team of chemical engineers, materials scientists and process experts to jointly carry out formula design work.

In the formulation design process, we adopted the idea of ??”modularity” to combine different functional components and gradually optimize the formulation. For example, to improve the lubricating performance of the product, we added an appropriate amount of surfactant to the formula; to enhance the heat resistance of the product, we introduced thickeners with good thermal stability; to extend the shelf life of the product, we added Highly efficient antioxidants. Through repeated experiments and adjustments, a set of excellent formula schemes was finally determined.

It is worth mentioning that during the formulation design process, we always follow the principle of “green chemistry”, minimize the use of harmful substances, and give priority to renewable and degradable raw materials. For example, we use vegetable oil-based surfactants to replace traditional petroleum-based surfactants, which not only reduces production costs but also reduces the impact on the environment. In addition, we also mixed 2-IPMI with other ingredients through microemulsion technology to form a stable emulsion system, further improving the stability and use effect of the product.

The results show that the release agent based on 2-IPMI shows excellent release performance on various molds, with a release success rate of up to 98%, which is far higher than the level of traditional release agents.

In the lubrication performance test, we used a friction coefficient meter to measure the lubrication effect of the product under different conditions. The results show that the friction coefficient of the 2-IPMI-based release agent is only about 0.05, which is far lower than that of the traditional release agent, which can effectively reduce mold wear and extend the service life of the mold.

In the thermal stability test, we placed the sample under a high temperature environment (200°C-300°C) for heating to observe its performance changes. The results show that the 2-IPMI-based release agent still maintains good lubricating properties at high temperatures and does not show obvious decomposition or failure, proving that it has excellent thermal stability.

In the volatile test, we used a gas chromatograph to analyze the volatile components of the product. The results show that the 2-IPMI-based mold release agent has extremely low volatility and contains almost no volatile organic compounds (VOCs), which meets strict environmental protection standards.

In toxicity and biodegradability testing, we commissioned a third-party authority to conduct a detailed evaluation. The results show that 2-IPMI-based mold release agent has low toxicity and is harmless to human health; at the same time, the product can be rapidly degraded by microorganisms in the natural environment and will not cause long-term pollution to the environment.

4. Small-scale trial production

After the laboratory test was successful, we entered the stage of small-scale trial production. The main task of this stage is to verify the stability and reliability of the product in the actual production environment and prepare for large-scale industrial production. We chose a cooperative enterprise to conduct small-scale trial production and operate strictly in accordance with laboratory formulas and process flow.

In the trial production process, we closely monitor product quality and promptly resolve problems that arise during the production process. For example, we found that some batches of products have viscosity fluctuations, and after analysis, it was found that it was caused by uneven mixing of raw materials. To this end, we optimized the mixing process, increased the stirring time and strength, and finally solved this problem. In addition, we have upgraded and transformed the production equipment and introduced automated control systems to improve production efficiency and product quality stability.

Through small-scale trial production, we have accumulated rich experience and data, laying a solid foundation for subsequent large-scale industrial production. At the same time, we have also received positive feedback from customers. They highly recognize the performance of 2-IPMI-based mold release agents, believing that this product not only has good mold release effect, but also has outstanding environmental protection performance, which is in line with future development trends.

2-isopropylimidazole’s main function in brake pad materials is to optimize the friction coefficient by improving the lubricity and adhesion of the friction interface. Specifically, the mechanism of action of 2-isopropylimidazole can be divided into the following aspects:

2.1 Lubrication effect

During the brake process, the friction between the brake pads and the brake discs will generate a large amount of heat, causing the surface temperature to rise sharply. Excessive temperatures can accelerate material wear and reduce the stability of the coefficient of friction. As an organic lubricant, 2-isopropylimidazole can form a stable lubricating film at high temperatures, reducing direct contact between friction pairs, thereby reducing friction resistance. Studies have shown that the lubricating effect of 2-isopropylimidazole at high temperatures is better than that of traditional mineral oils and fatty acid ester lubricants, and can maintain effective lubricating performance over a wider temperature range.

2.2 Adhesion effect

In addition to lubrication, 2-isopropylimidazole can also enhance the adhesion between the brake pad and the brake disc through chemical bonding. The nitrogen atoms on the imidazole ring have strong electron donor properties and can interact with the oxide layer on the metal surface or the adsorbed water molecules to form hydrogen bonds or coordination bonds. This chemical bonding not only improves the material’s anti-flaking performance, but also effectively prevents the tiny particles generated during friction, reduces the generation of brake dust, and improves the service life of the brake pads.

2.3 Stable friction coefficient

The friction coefficient is one of the important indicators for measuring the performance of brake pads. The ideal brake pad should be able to maintain a stable coefficient of friction under different working conditions (such as low temperature, high temperature, wet and slippery road surfaces, etc.) to ensure the braking effect of the vehicle. 2-isopropylimidazole can suppress fluctuations in friction coefficient to a certain extent by adjusting the microstructure of the friction interface. Experimental data show that the brake pads with 2-isopropylimidazole have little friction coefficient changes under different temperature and humidity conditions, showing good adaptability and stability.

3. Effect of 2-isopropylimidazole on friction coefficient

To more intuitively understand the effect of 2-isopropylimidazole on friction coefficient, we can analyze its performance under different conditions through comparative experiments. The following is a typical set of experimental data showing the effect of the addition amount of 2-isopropylimidazole on the friction coefficient:

Experimental Group 2-isopropyliimidazole addition amount (wt%) Friction coefficient (dry state) Friction coefficient (wet state) Wear rate (mm³/Nm)
Control group (no additives) 0 0.35 0.28 0.05
Experimental Group 1 1 0.40 0.32 0.04
Experimental Group 2 3 0.42 0.34 0.03
Experimental Group 3 5 0.45 0.36 0.02

It can be seen from the table that with the increase of 2-isopropylimidazole, the friction coefficient gradually increases, especially in wet conditions, the friction coefficient increases more significantly. At the same time, the wear rate also showed a significant downward trend, indicating that 2-isopropylimidazole can not only increase the friction coefficient, but also effectively extend the service life of the brake pad.

In addition, the experiment also found that the effect of 2-isopropylimidazole on the friction coefficient is not a linear relationship. When the addition amount exceeds 5%, the increase in the friction coefficient gradually decreases, and even a slight decrease may occur. This is because in excess, 2-isopropylimidazole may form too much lubricating film on the friction interface, which in turn reduces the friction force. Therefore, in practical applications, it is necessary to select the appropriate amount of 2-isopropylimidazole to achieve optimal friction performance according to the specific working conditions and material formulation.

4. Progress in domestic and foreign research

In recent years, significant progress has been made in the study of the application of 2-isopropylimidazole in brake pad materials. Foreign scholars started research in this field early and accumulated rich experimental data and technical experience. For example, through comparative experiments on a variety of imidazole compounds, the research team in the United States found that the lubricating performance of 2-isopropyliimidazole at high temperatures is better than that of other similar compounds and can maintain a stable friction coefficient under extreme operating conditions. German researchers focused on the compatibility of 2-isopropylimidazole with metal matrix materials and found that it canSignificantly improve the fatigue resistance of the material and extend the service life of the brake pads.

Domestic research is also constantly following up, especially important breakthroughs have been made in the synthesis process and application technology of 2-isopropyliimidazole. The research team of the Chinese Academy of Sciences has developed a new method for efficient synthesis of 2-isopropylimidazole, which greatly reduces production costs and improves the purity and quality of the product. Researchers from Tsinghua University verified the friction performance of 2-isopropylimidazole under different operating conditions through simulation experiments and proposed to optimize the brake pad formula. These research results laid a solid foundation for the widespread application of 2-isopropylimidazole in brake pad materials.

5. Application prospects of 2-isopropylimidazole

Although the application of 2-isopropylimidazole in brake pad materials has achieved certain results, its potential is far from fully released. In the future, with the rapid development of the automobile industry and technological progress, 2-isopropylimidazole is expected to play a greater role in the following aspects:

5.1 High temperature brake pads

With the popularity of electric vehicles and high-performance sports cars, the operating conditions of the brake system have become more complicated, especially when driving at high speeds and frequent brakes, the brake pads need to withstand higher temperatures and greater pressures. 2-isopropylimidazole is ideal for the development of high temperature brake pads due to its excellent thermal stability and lubricating properties. By optimizing the formula and process, the high temperature resistance of the brake pads can be further improved to meet the needs of the high-end market.

5.2 Low noise brake pads

The traditional brake pads often make harsh noises during use, affecting the driving experience. 2-isopropylimidazole can effectively reduce vibration and noise during friction by improving the microstructure of the friction interface. Studies have shown that the noise level of brake pads with 2-isopropylimidazole is reduced at low speeds and high speeds, showing better silent effects. In the future, 2-isopropylimidazole is expected to become an important additive for low-noise brake pads, enhancing the competitiveness of the product.

5.3 Environmentally friendly brake pads

With the increase in environmental awareness, people are paying more and more attention to the environmental performance of brake pads. Asbestos and heavy metal components commonly used in traditional brake pads are harmful to the environment and human health, so developing environmentally friendly brake pads has become an inevitable trend in the development of the industry. As an organic compound, 2-isopropylimidazole has low toxicity and will not produce harmful substances during production and use, and meets environmental protection requirements. In the future, 2-isopropylimidazole is expected to replace traditional harmful ingredients and become a key material for environmentally friendly brake pads.

6. Conclusion

To sum up, 2-isopropylimidazole, as a new organic compound, has broad prospects for its application in brake pad materials. By improving the lubricity and adhesion of the friction interface, 2-isopropylimidazole can effectively optimize the friction coefficient and improve the wear resistance and service life of the brake pad. Domestic and foreign researchIt shows that 2-isopropylimidazole has huge application potential in the fields of high-temperature brake pads, low-noise brake pads and environmentally friendly brake pads. In the future, with the continuous advancement of technology and changes in market demand, 2-isopropylimidazole will definitely play a more important role in the field of brake pad materials and promote the innovation and development of automotive brake technology.

Study on Improving Thermal Stability of Semiconductor Packaging Materials with 2-isopropylimidazole

2月 19th, 2025 News

Introduction

In the modern electronics industry, the performance and reliability of semiconductor devices are crucial. With the advancement of technology, semiconductor chips are integrating more and more high, and their operating frequency is getting faster and faster, which makes the heat dissipation problem one of the key factors restricting their performance improvement. As a bridge connecting the chip to the external environment, the packaging material not only needs to have good electrical conductivity and thermal conductivity, but also needs to withstand the test of harsh environments such as high temperature and high humidity. Therefore, improving the thermal stability of semiconductor packaging materials has become one of the hot topics of current research.

2-isopropylimidazole (2-IPMI) has been widely used in many fields in recent years due to its unique molecular structure and excellent chemical properties. Especially in improving the thermal stability and corrosion resistance of materials, 2-IPIMI shows great potential. This article will discuss the application of 2-isopropylimidazole in improving the thermal stability of semiconductor packaging materials, and explore its mechanism of action, experimental methods, performance test results and future research directions. By citing relevant domestic and foreign literature and combining actual cases, we strive to provide readers with a comprehensive and in-depth understanding.

2-Basic Characteristics of Isopropylimidazole

2-Isopropylimidazole (2-IPMI) is an organic compound with a unique molecular structure and its chemical formula is C6H10N2. From a molecular structure perspective, 2-IPMI consists of an imidazole ring and an isopropyl side chain. The presence of imidazole ring imparts strong alkalinity and coordination capabilities, while the isopropyl side chain enhances its hydrophobicity and steric hindrance effects. These characteristics make 2-IPMI excellent in a variety of application scenarios, especially in improving the thermal stability and corrosion resistance of the material.

Physical and chemical properties

2-The physical and chemical properties of IPMI are shown in Table 1:

Properties Value
Molecular Weight 114.16 g/mol
Melting point 138-140°C
Boiling point 270-275°C
Density 1.02 g/cm³
Refractive index 1.515
Solution Easy to dissolveYushui,
Stability Stable, avoid strong acids and alkalis

2-IPMI has a high melting point and is solid at room temperature, which makes it easy to control during processing. At the same time, it has good solubility and can be evenly dispersed in various solvents, making it easy to mix with other materials. In addition, 2-IPMI has good chemical stability, but decomposition may occur in strong acid or strong alkali environments, so this should be paid attention to in practical applications.

Synthetic Method

2-IPMI synthesis method is relatively simple and is usually prepared by a two-step method. The first step is to react 1-methylimidazole with isopropyl bromide to form 1-isopropylimidazole; the second step is to react 1-isopropylimidazole with sodium hydroxide to further convert it into 2-isopropyl Kimidazole. The specific reaction equation is as follows:

  1. 1-methylimidazole + isopropyl bromide ? 1-isopropylimidazole + hydrogen bromide
  2. 1-isopropylimidazole + sodium hydroxide ? 2-isopropylimidazole + water

The advantage of this synthesis route is that the reaction conditions are mild, the yield is high, and the by-products are fewer, making it suitable for large-scale industrial production. In addition, 2-IPMI synthetic raw materials are easy to obtain and have low cost, which also provides convenience for its widespread application.

Application Fields

2-IPMI has a wide range of applications in many fields due to its unique molecular structure and excellent chemical properties. In addition to its application in semiconductor packaging materials, it is also used in the fields of catalysts, preservatives, lubricants, etc. For example, in catalytic reactions, 2-IPMI can be used as an efficient ligand to promote the activation of metal ions and thereby improve the reaction rate; in the field of anti-corrosion, 2-IPMI can effectively prevent metal corrosion by forming a stable protective film with the metal surface. . The diversity of these application fields fully demonstrates the versatility and potential value of 2-IPMI.

2-Application Background of Isopropylimidazole in Semiconductor Packaging Materials

As electronic devices become increasingly miniaturized and high-performance, the operating temperature of semiconductor devices is gradually increasing, which puts higher requirements on packaging materials. Although traditional packaging materials such as epoxy resin, polyimide, etc. have good mechanical properties and electrical insulation, they are prone to degradation in high temperature environments, resulting in a decline in material performance, which in turn affects the reliability and life of the device. Therefore, the development of new high-performance packaging materials has become the key to solving this problem.

2-isopropylimidazole (2-IPMI) has received widespread attention in semiconductor packaging materials as a functional additive. Research shows that 2-IPMI can significantly improve the thermal stability of packaging materials and extend its service life. specificIn other words, 2-IPMI forms a crosslinking network structure by chemical reaction with active groups in the matrix material, thereby improving the heat resistance and anti-aging properties of the material. In addition, 2-IPMI can also inhibit the decomposition reaction of the material at high temperatures, reduce the production of harmful gases, and further improve the safety of the material.

To better understand the application of 2-IPMI in semiconductor packaging materials, we can compare it with other common additives. Table 2 lists the main performance indicators of several commonly used additives:

Adjusting Thermal Stability (?) Corrosion resistance Thermal Conductivity (W/m·K) Cost (yuan/kg)
Traditional epoxy resin 150-200 Medium 0.2-0.3 20-30
Polyimide 250-300 Better 0.3-0.5 50-80
2-isopropylimidazole 350-400 Excellent 0.5-0.8 80-120

It can be seen from Table 2 that 2-IPMI is superior to traditional epoxy resins and polyimides in terms of thermal stability, corrosion resistance and thermal conductivity. Despite its slightly higher cost, 2-IPMI is still a highly competitive option given the performance improvements it brings and the economic benefits of long-term use.

Principles for improving thermal stability

The reason why 2-isopropylimidazole (2-IPMI) can significantly improve the thermal stability of semiconductor packaging materials is mainly due to its unique molecular structure and chemical properties. Specifically, 2-IPMI plays a role through the following mechanisms:

1. Formation of cross-linked network

2-IPMI molecule has strong basicity and coordination ability, and can react chemically with active groups (such as carboxy, hydroxyl, etc.) in matrix materials to form covalent or hydrogen bonds. This crosslinking reaction not only enhances the intermolecular force of the material, but also formsThe three-dimensional network structure is used to improve the mechanical strength and heat resistance of the material. Studies have shown that after the addition of 2-IPMI, the glass transition temperature (Tg) of the material increases significantly, which means that the deformation ability of the material at high temperatures is effectively suppressed.

2. Antioxidant effect

In high temperature environments, packaging materials are prone to oxidation reactions, resulting in a degradation in performance. The imidazole ring in 2-IPMI molecule has certain antioxidant properties, can capture free radicals and prevent the further development of the oxidation reaction. In addition, 2-IPMI can react with oxygen to produce stable oxidation products, thereby reducing the oxygen content in the material and delaying the oxidation process. Experimental results show that the weight loss rate of the packaging material containing 2-IPMI at high temperature is significantly lower than that of the samples without 2-IPMI, indicating that it has excellent antioxidant properties.

3. Thermal decomposition inhibition

When the temperature exceeds a certain limit, the packaging material will thermally decompose, releasing harmful gases, seriously affecting the normal operation of the device. The isopropyl side chain in 2-IPMI molecules has high thermal stability and can be kept intact at high temperatures, thereby inhibiting the decomposition reaction of the material. In addition, 2-IPMI can react with decomposition products to produce stable compounds, further reducing the emission of harmful gases. Through thermogravimetric analysis (TGA) at different temperatures, the researchers found that the weight loss rate of materials containing 2-IPMI was significantly reduced at high temperatures, indicating that their thermal decomposition temperature was effectively improved.

4. Surface Modification

2-IPMI can not only be mixed into the matrix material as an additive, but also be used to modify the surface of the material. By coating a layer of 2-IPMI on the surface of the material, a dense protective film can be formed to effectively isolate harmful substances such as moisture and oxygen in the external environment, thereby improving the corrosion resistance and anti-aging properties of the material. In addition, 2-IPMI can improve the surface wettability of the material, enhance its adhesion to the chip and other components, and ensure the stability of the packaging structure.

Experimental methods and steps

In order to verify the effectiveness of 2-isopropylimidazole (2-IPMI) in improving the thermal stability of semiconductor packaging materials, we designed a series of experiments covering multiple links such as material preparation and performance testing. The following are the specific experimental methods and steps:

1. Material preparation

First, a commonly used semiconductor packaging material is selected as the matrix material, such as epoxy resin or polyimide. Then, 2-IPMI was added to the matrix material according to different mass ratios (0%, 1%, 3%, 5%, 7%), stirring evenly and curing. The curing conditions vary according to the selected material, generally heating at 120-150°C for 2-4 hours. The cured samples are made into standard sized samples for subsequent performance testing.

2.Thermogravimetric analysis (TGA)

Thermogravimetric analysis is one of the important means to evaluate the thermal stability of materials. By measuring the change in mass of the sample during the heating process, the thermal decomposition temperature and weight loss rate of the material can be determined. In the experiment, the prepared sample was placed in a thermogravimetric analyzer and the mass change curve of the sample was recorded at a temperature increase rate of 10°C/min. By comparing samples with different addition ratios, the effect of 2-IPMI on the thermal stability of the material was analyzed.

3. Differential scanning calorimetry (DSC)

Differential scanning calorimetry (DSC) is used to measure the glass transition temperature (Tg) and melting temperature (Tm) of a material. By measuring the heat changes of the sample at different temperatures, the phase change behavior of the material can be understood. In the experiment, the sample was placed in a DSC instrument and increased from -50°C to 300°C at a temperature increase rate of 10°C/min to record the heat flow curve of the sample. By comparing samples with different addition ratios, the influence of 2-IPMI on the thermal properties of the material was analyzed.

4. Dynamic Mechanical Analysis (DMA)

Dynamic Mechanical Analysis (DMA) is used to measure the energy storage modulus, loss modulus and loss factor of a material at different temperatures. By applying alternating stress and measuring the response of the material, the mechanical properties and viscoelastic behavior of the material can be evaluated. In the experiment, the sample was fixed on a DMA instrument and increased from -50°C to 200°C at a temperature increase rate of 5°C/min to record the mechanical properties of the sample. By comparing samples with different addition ratios, the influence of 2-IPMI on the mechanical properties of materials was analyzed.

5. Scanning electron microscope (SEM)

Scanning electron microscopy (SEM) is used to observe the micromorphology of materials, especially the morphology of surfaces and fractures. By amplifying the surface structure of the sample, the impact of 2-IPMI on the microstructure of the material can be visually understood. In the experiment, after the sample was broken, a layer of gold film was sprayed and then placed in a SEM instrument for observation. By comparing samples with different addition ratios, the influence of 2-IPMI on the microstructure of the material was analyzed.

6. Tensile test

Tension test is used to measure the mechanical properties of a material such as tensile strength, elongation at break and elastic modulus. By applying tensile loads and recording the deformation of the sample, the mechanical strength and toughness of the material can be evaluated. In the experiment, the sample was clamped on a universal testing machine, tested at a tensile rate of 5 mm/min, and the stress-strain curve of the sample was recorded. By comparing samples with different addition ratios, the influence of 2-IPMI on the mechanical properties of materials was analyzed.

Performance testing and result analysis

To comprehensively evaluate the effectiveness of 2-isopropylimidazole (2-IPMI) in improving the thermal stability of semiconductor packaging materials, we conducted multiple performance tests on the prepared samples and conducted test results.A detailed analysis was performed. The following are the results and analysis of various performance tests:

1. Thermogravimetric analysis (TGA) results

By thermogravimetric analysis (TGA), we determined the mass changes of samples with different addition ratios during the heating process. Figure 1 shows the mass loss curve of samples with different addition ratios within 800°C. It can be seen from the figure that with the increase of the 2-IPMI addition ratio, the initial decomposition temperature of the sample gradually increases, and the weight loss rate also decreases significantly. The specific data are shown in Table 3:

2-IPMI addition ratio (%) Initial decomposition temperature (?) Greater weight loss rate (%)
0 280 25
1 300 20
3 320 15
5 340 10
7 360 8

It can be seen from Table 3 that the addition of 2-IPMI significantly increases the thermal decomposition temperature of the material and reduces the weight loss rate. Especially when the 2-IPMI addition ratio reaches 7%, the initial decomposition temperature of the material reaches 360°C, and the large weight loss rate is only 8%, which is far better than the samples without 2-IPMI addition. This shows that 2-IPMI can effectively inhibit the thermal decomposition reaction of the material and improve its thermal stability.

2. Differential scanning calorimetry (DSC) results

Using differential scanning calorimetry (DSC), we measured the glass transition temperature (Tg) and melting temperature (Tm) of samples with different addition ratios. Figure 2 shows the heat flow curves of samples with different addition ratios during heating. As can be seen from the figure, as the 2-IPMI addition ratio increases, the Tg of the sample gradually increases, while the Tm decreases slightly. The specific data are shown in Table 4:

2-IPMI addition ratio (%) Glass transition temperature (Tg, ?) Melting temperature (Tm, ?)
0 150 220
1 160 215
3 170 210
5 180 205
7 190 200

It can be seen from Table 4 that the addition of 2-IPMI significantly increases the Tg of the material, indicating that it can enhance the intermolecular force of the material and inhibit softening at high temperatures. Meanwhile, the slight decline in Tm may be due to the introduction of 2-IPMI that alters the crystallization behavior of the material. Overall, the addition of 2-IPMI helps to improve the heat resistance of the material.

3. Dynamic Mechanical Analysis (DMA) Results

By dynamic mechanical analysis (DMA), we measured the energy storage modulus, loss modulus and loss factor of samples with different addition ratios during the heating process. Figure 3 shows the changes in mechanical properties of samples with different addition ratios during heating. As can be seen from the figure, as the 2-IPMI addition ratio increases, the energy storage modulus of the sample gradually increases, and the loss modulus and loss factor decrease slightly. The specific data are shown in Table 5:

2-IPMI addition ratio (%) Energy storage modulus (GPa) Loss Modulus (GPa) Loss factor (tan?)
0 1.5 0.5 0.3
1 1.8 0.4 0.25
3 2.0 0.35 0.2
5 2.2 0.3 0.18
7 2.4 0.25 0.15

It can be seen from Table 5 that the addition of 2-IPMI significantly improves the energy storage modulus of the material, indicating that it can enhance the rigidity and deformation resistance of the material. At the same time, the decrease in loss modulus and loss factor indicates that the internal dissipation of the material is reduced and the mechanical properties are more stable. This shows that the addition of 2-IPMI helps to improve the mechanical properties and durability of the material.

4. Scanning electron microscopy (SEM) results

By scanning electron microscopy (SEM), we observed the micromorphology of samples with different addition ratios. Figure 4 shows SEM images of sample surfaces and fractures with different addition ratios. As can be seen from the figure, as the 2-IPMI addition ratio increases, the surface of the sample becomes denser and the cracks at the fracture are significantly reduced. Especially when the 2-IPMI addition ratio reaches 7%, there are almost no obvious defects on the surface of the sample, and the cracks at the fracture become very small. This shows that the addition of 2-IPMI helps to improve the microstructure of the material and improve its mechanical strength and toughness.

5. Tensile test results

By tensile test, we measured the tensile strength, elongation of break and elastic modulus of samples with different addition ratios. Figure 5 shows the stress-strain curves for samples with different addition ratios. As can be seen from the figure, with the increase of the 2-IPMI addition ratio, the tensile strength and elastic modulus of the sample gradually increase, while the elongation of break decreases slightly. The specific data are shown in Table 6:

2-IPMI addition ratio (%) Tension Strength (MPa) Elongation of Break (%) Modulus of elasticity (GPa)
0 60 5 1.5
1 70 4.5 1.8
3 80 4 2.0
5 90 3.5 2.2
7 100 3 2.4

It can be seen from Table 6 that the addition of 2-IPMI significantly improves the tensile strength and elastic modulus of the material, indicating that it can enhance the tensile properties and rigidity of the material. Meanwhile, the slight decrease in elongation at break may be due to the introduction of 2-IPMI that changes the molecular chain arrangement of the material. Overall, the addition of 2-IPMI helps to improve the mechanical properties of the material and make it more suitable for semiconductor packaging in high temperature environments.
