The “stabilizer” in electric vehicle charging facilities–N,N-dimethylamine

With the transformation of the global energy structure and the improvement of environmental awareness, electric vehicles (Electric Vehicle, EV) have become the core trend in the development of the automotive industry. As a key infrastructure supporting the operation of electric vehicles, the performance and stability of charging facilities are directly related to the user’s driving experience and the popularity of electric vehicles. However, in complex usage environments, charging equipment may be affected by multiple factors such as temperature changes, humidity fluctuations, and chemical corrosion, resulting in performance degradation and even frequent failures. To solve this problem, researchers have turned their attention to an efficient and versatile compound – N,N-dimethylamine (DMEA for short). With its unique chemical characteristics and excellent stability, this compound has gradually become a secret weapon to ensure the long-term and reliable operation of charging facilities.

This article aims to comprehensively analyze the application value of N,N-dimethylamine in electric vehicle charging facilities, start from its basic characteristics, and deeply explore its specific role in anti-corrosion, anti-aging and improving system efficiency. It is also combined with relevant domestic and foreign literature and actual cases to provide readers with a detailed technical guide. The article will also present key parameters and experimental data in the form of tables, striving to make the content easy to understand, while being scientific and interesting. Whether you are an ordinary reader who is interested in the electric vehicle field or a professional engaged in related technology research and development, this article will uncover the mystery of how DMEA can help charging facilities achieve “longevity”.

Basic Characteristics of N,N-dimethylamine

N,N-dimethylamine is an organic compound with the chemical formula C4H11NO. It is a product produced by reaction of amine with dihydrogen, with a primary amino group and a hydroxyl functional group, which gives it unique chemical properties. At room temperature, DMEA is a colorless liquid with a slight ammonia odor, its density is about 0.93 g/cm³, and its boiling point is about 165°C. These physical properties make DMEA outstanding in a variety of industrial applications.

DMEA has extremely high chemical stability and can remain relatively stable even in high temperature or acid-base environments. This is because its molecular structure contains two methyl substituents, which can effectively shield the amino group and reduce the possibility of it reacting with other substances. In addition, DMEA also exhibits good solubility, which is both soluble in water and compatible with many organic solvents, which provides convenience for its application in different environments.

Chemical Reaction Activity

The chemical reactivity of DMEA is mainly reflected in its amino and hydroxyl groups. The amino group allows it to participate in acid-base reactions to form salts or aminations; while the hydroxyl group gives it a certain amount of hydrophilicity and can undergo esterification reaction with acidic substances. These properties make DMEA play an important role in the preparation of corrosion inhibitors, catalysts and other chemical products.

Environmental adaptability

DMEA has extremely strong environmental adaptability and can maintain its function over a wide range of temperature and humidity. For example, at low temperatures, DMEA does not solidify as easily as some other amine compounds, and at high temperatures, it does not decompose quickly. This excellent environmental adaptability is particularly important for application scenarios that require long-term stability, such as electrolyte additives in electric vehicle charging facilities.

To sum up, N,N-dimethylamine has become one of the indispensable multifunctional compounds in modern industry due to its stable chemical properties, good solubility and excellent environmental adaptability. These characteristics not only determine their important position in laboratory research, but also pave the way for their practical use.

Advantages of application in charging facilities

N,N-dimethylamine (DMEA) as a multifunctional compound has shown significant advantages in the use of electric vehicle charging facilities. Below we will discuss the role and uniqueness of DMEA from three aspects: anti-corrosion protection, anti-aging performance and improving system efficiency.

Anti-corrosion protection

Charging facilities are usually exposed to various harsh natural environments, including rainwater erosion, salt spray corrosion and ultraviolet radiation. These factors can accelerate the aging and damage of metal parts, affecting the overall life and safety of the equipment. Because DMEA contains amine groups and hydroxyl groups in its molecular structure, it can form a dense protective film with the metal surface, effectively preventing the invasion of harmful substances from outside. This protection mechanism is similar to wearing a “invisible protective clothing” on metal, greatly delaying the occurrence of the corrosion process.

Features Description
Reduced corrosion rate DMEA can reduce the corrosion rate of metal surfaces to below 20%
Environmental Adaptation Excellent performance in high humidity and salt spray environments

Anti-aging properties

In addition to the influence of the external environment, the electronic components inside the charging facilities will also age over time. As an antioxidant, DMEA can neutralize free radicals and slow down the aging process of materials. Specifically, DMEA maintains the mechanical strength and electrical properties of the material by capturing free radicals, preventing them from attacking the polymer chain. This feature is critical to ensuring long-term reliability of charging cables, connectors and other plastic components.

Performance metrics Improvement
Tenable strength of material About 15%
Insulation resistance value Add more than 20%

Improving system efficiency

During the charging process, the conductivity and thermal management capabilities of the electrolyte directly affect the charging speed and battery life. After DMEA is added to the electrolyte, it can not only improve the ion conductivity of the solution, but also help regulate the temperature distribution and avoid the occurrence of local overheating. This optimization helps to shorten charging time and extend battery life, thereby improving the operating efficiency of the entire system.

parameters Effect
Charging time Average reduction of 10%-15%
Battery cycle life Extend about 25%

To sum up, the application of DMEA in electric vehicle charging facilities has demonstrated its advantages in many aspects. Whether it is protection of the external environment, suppressing the aging of internal components, or improving the overall system efficiency, DMEA has played an irreplaceable role. These characteristics make DMEA an ideal choice to ensure the long-term and stable operation of charging facilities.

Future development and potential challenges

Although the application of N,N-dimethylamine (DMEA) in electric vehicle charging facilities has shown many advantages, a series of technical and market challenges are still required to achieve its larger-scale promotion and deeper application. The following will discuss the future development direction of DMEA from three dimensions: technological improvement, cost control and market demand.

Technical Improvement

Currently, the application of DMEA in charging facilities is mainly concentrated in the fields of corrosion and anti-aging, but its potential functions are far from fully explored. For example, by optimizing the synthesis process or introducing nanotechnology, the chemical stability and functionality of DMEA can be further improved. In addition, customizing the development of specific formula DMEA products for different types of charging devices will also become a major trend. Future research priorities may include developing higher concentrations of DMEA solutions to enhance their efficacy while reducing their environmental impact. Scientists are also actively exploring how to use bioengineering technology to produce DMEA, which can not only reduce production costs, but also reduce dependence on petrochemical resources.

Cost Control

Although DMEA has superior performance, its relatively high cost is still one of the main factors that restrict its widespread use. Therefore, reducing costs is an important strategy to promote the marketization of DMEA. On the one hand, unit manufacturing costs can be reduced through large-scale production and optimization of the supply chain; on the other hand, more efficient DMEA derivatives can be developed to achieve the same or even better results with a smaller amount, thereby indirectly reducing the overall usage costs. In addition, policy support such as tax incentives or subsidy measures may also alleviate financial pressure on enterprises to a certain extent and promote the popularization of DMEA.

Market Demand

As the global emphasis on sustainable development increases and the rapid growth of the electric vehicle market, the demand for charging facilities has also surged. This means that high-performance materials such as DMEA have broad market prospects. However, how to accurately grasp market demand and timely adjust product strategies is an issue that needs continuous attention. Enterprises should strengthen communication with end users and gain insight into the specific problems they encounter in actual operations, so as toThis will improve products and services more targetedly. At the same time, establishing a complete after-sales service system and providing technical support and training are also important means to enhance customer stickiness.

In short, although the application of DMEA in electric vehicle charging facilities faces some challenges, through continuous technological innovation, effective cost management and precise market positioning, I believe DMEA can play a more important role in the future green energy revolution. As an industry expert said: “DMEA is not just a chemical, it is a key to a cleaner and more efficient future.”

The application of polyurethane catalyst DBU in the floor coating of sports venues to improve athlete performance

3月 18th, 2025 News

Polyurethane Catalyst DBU: “Secret Weapon” in the Ground Coating of Stadiums

In the construction of modern stadiums, the ground coating is the first interface between athletes and the field, and its performance directly affects the athlete’s performance and competition experience. The polyurethane catalyst DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) plays a crucial role in the application of floor coatings in stadiums. It not only significantly improves the curing speed of the coating, but also optimizes the physical properties of the coating, thus providing athletes with a better sports environment.

1. Basic characteristics of DBU and its role in polyurethane systems

DBU is a strong basic catalyst with unique molecular structure and excellent catalytic properties. Its chemical name is 1,8-diazabicyclo[5.4.0]undec-7-ene, the molecular formula is C7H12N2, and the molecular weight is 124.18. The melting point of DBU is 163?~165?, the boiling point is 270?, the density is 1.02g/cm³ (20?), and is easily soluble in water and most organic solvents. These properties allow DBU to exhibit excellent catalytic effects in polyurethane reaction systems.

(I) The mechanism of action of DBU in polyurethane reaction

In polyurethane systems, DBU accelerates the curing process mainly by promoting the reaction between isocyanate (NCO) and polyol (OH). Specifically, DBU can reduce the reaction activation energy and enable the reaction to proceed rapidly at lower temperatures. In addition, DBU can effectively inhibit the occurrence of side reactions, thereby improving the uniformity and stability of the coating.

Table 1: Comparison of performance of DBU and other common catalysts

Catalytic Type Activity level Response Selectivity Stability
DBU High Strong Excellent
Organic tin in Winner General
Metal chelates Low Poor Poor

As can be seen from Table 1, DBU is superior to other common catalysts in terms of activity, reaction selectivity and stability, making it an ideal choice for floor coatings in stadiums.

(II) Effect of DBU on coating performance

DBU can not onlyAccelerating the curing speed of polyurethane coatings can also significantly improve the mechanical properties and durability of the coating. Studies have shown that polyurethane coatings with appropriate amounts of DBU have higher hardness, better wear resistance and stronger impact resistance. These properties are particularly important for stadium floors, as they require high intensity use and frequent cleaning and maintenance.

2. Advantages of DBU in floor coating of stadiums

With the continuous increase in venue requirements for modern sports events, DBU’s application in the floor coating of stadiums has shown many unique advantages. The following will discuss the application value of DBU in detail from three aspects: construction efficiency, environmental performance and sports performance.

(I) Improve construction efficiency

During the construction of the floor coating of the stadium, the curing speed of the coating directly affects the overall construction period. Although traditional catalysts such as organotin can also promote curing, their reaction speed is slow and are easily affected by environmental humidity. Due to its efficient catalytic properties, DBU can complete coating curing in a short time, greatly shortening the construction cycle. For example, in a construction project of an international track and field field, a polyurethane coating catalyzed with DBU takes only 6 hours to achieve walking strength, while a traditional process takes more than 24 hours.

(II) Enhanced environmental performance

In recent years, environmental protection issues have attracted increasing attention, and the construction of sports venues is no exception. As a non-toxic and odorless catalyst, DBU fully meets the requirements of green and environmental protection. In contrast, organic tin catalysts may release harmful substances, posing a potential threat to construction workers and the environment. Therefore, the use of DBU not only improves coating performance, but also reduces the negative impact on the environment.

(III) Optimize sports performance

The improvement of DBU’s performance on polyurethane coating is directly related to the athlete’s performance. The DBU-catalyzed coating has lower coefficient of friction and higher elastic recovery, which allows athletes to obtain better grip and energy feedback during movements such as running and jumping. Taking the basketball court as an example, after using DBU-catalyzed polyurethane coating, athletes’ jump height increased by an average of 5%, and slip accidents decreased by 30%.

3. Analysis of application case of DBU in different sports venues

In order to better illustrate the practical application effect of DBU, the following are selected for case analysis.

(I) Football Stadium

Football field floor coating needs to have good elasticity and wear resistance to meet long-term game needs. A top European football club has used DBU-catalyzed polyurethane coating in its home renovation project. The results show that the service life of the new coating is 50% longer than that of the traditional coating, and players generally report that the foot feels more comfortable.

(II) Tennis Court

The anti-slip properties of tennis court floor coatings are crucial, especially after rain or tideIn wet environment. After using DBU catalyzed coatings in an international tennis open venue, athletes can still maintain a stable pace even when rainwater hits, greatly improving the safety and ornamentality of the game.

(Three) Runway

The track and field tracks require extremely high impact resistance and durability of coatings. A world-class track and field championship venue introduced DBU technology during construction, and finally achieved the goal of zero cracks and zero peeling, which was highly praised by the contestants.

IV. Technical parameters and selection guide for DBU

For users who want to apply DBU in stadium floor coatings, it is very important to understand its technical parameters and selection criteria.

Table 2: Main technical parameters of DBU

parameter name Unit Value Range
Appearance – White crystalline powder
Melting point ? 163~165
Content % ?99
Moisture % ?0.1
Ash % ?0.1

When choosing DBU, it is recommended to adjust the dosage according to the specific construction conditions and coating requirements. Generally speaking, the amount of DBU is 0.1% to 0.5% of the total amount of polyurethane. Excessive use may cause bubbles or cracks on the surface of the coating, affecting the final effect.

5. Current status and development prospects of domestic and foreign research

In recent years, research on the application of DBU in polyurethane systems has achieved fruitful results. Foreign scholars have focused on the impact of DBU on the microstructure of coatings, while domestic research has focused more on its practical application effects. For example, a research team from a university in the United States found through scanning electron microscopy that a denser network structure is formed inside the coating catalyzed by DBU, which is the fundamental reason for its superior performance.

Looking forward, with the development of nanotechnology, DBU is expected to be combined with nanomaterials to further improve coating performance. At the same time, the popularity of intelligent construction equipment will also provide more possibilities for the application of DBU.

VI. Conclusion

To sum up, polyurethane catalyst DBU has its excellent catalytic performance and environmental protectionAdvantages have become a star product in the field of floor coatings of stadiums. Whether from the perspective of construction efficiency, environmental performance or sports performance, DBU has shown unparalleled value. I believe that in the future, with the continuous advancement of technology, DBU will play a greater role in more fields and create a better living environment for mankind.

As a famous saying goes, “Details determine success or failure.” In the seemingly ordinary field of stadium floor coating, DBU interprets this truth with its precise catalytic effect. Let us look forward to more exciting performances of DBU in the future stadium construction!

Polyurethane catalyst DBU optimizes the antioxidant capacity of food packaging materials and ensures food safety

3月 18th, 2025 News

1. Antioxidant challenge of food packaging materials: an invisible “defense war”

In today’s fast-paced lifestyle, food packaging has become an important barrier to ensuring food safety and quality. However, as people’s requirements for food shelf life continue to increase, the antioxidant challenges faced by food packaging materials are becoming increasingly severe. Just like a loyal guardian, food packaging must not only resist the erosion of the external environment, but also prevent the damage caused to food by internal chemical reactions. Among them, antioxidant capacity is a crucial line of defense in this “defense battle”.

The oxidation problem of food packaging materials is like an enemy lurking in the dark, quietly threatening the safety and quality of food. The invasion of oxygen will trigger a series of complex chemical reactions, resulting in deterioration of food flavor, loss of nutrients, and even the production of harmful substances. For example, oily and fat foods will produce an unpleasant odor when oxidized in the packaging; juices rich in vitamin C will also be greatly reduced after being exposed to air. These changes not only affect consumers’ edible experience, but also may have potential health hazards.

To address this challenge, scientists have continuously explored ways to improve the antioxidant properties of food packaging. The polyurethane catalyst DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) has shown unique application potential in this field as an efficient functional additive. It is like a wise commander, which gives food packaging materials excellent antioxidant ability through precise regulation of polymerization. This catalyst not only significantly improves the barrier properties of packaging materials, but also optimizes its physical and mechanical properties, allowing it to play an important role in protecting food from oxidation.

This article will deeply explore the application principles and advantages of DBU in food packaging materials, and combine specific product parameters and domestic and foreign research results to comprehensively analyze how it can effectively improve the antioxidant performance of food packaging, so as to better ensure food safety. Let us unveil the mystery of this “behind the scenes” and witness its extraordinary performance in the field of food packaging.

2. Characteristics and mechanism of action of polyurethane catalyst DBU: Revealing the magical chemistry magician

Polyurethane catalyst DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) is an organic basic catalyst with a unique molecular structure. It is highly favored in many industrial fields due to its efficient catalytic performance and excellent selectivity. As a key additive for the modification of food packaging materials, DBU has become an ideal choice for improving packaging antioxidant properties due to its excellent chemical properties and unique reaction mechanism.

From the molecular structure, DBU consists of a rigid bicyclic backbone and two nitrogen atoms, and this special configuration gives it extremely high alkalinity and stability. Compared with other common amine catalysts, DBU exhibits stronger nucleophilicity and higher reactivity, which can effectively promote the reaction between isocyanate and polyol at lower temperatures.. This characteristic allows DBU to achieve faster curing speed and more uniform crosslinking density during polyurethane synthesis, thereby significantly improving the performance of the final product.

The mechanism of action of DBU is mainly reflected in the following aspects: First, it accelerates the reaction between isocyanate groups and hydroxyl groups, promotes the rapid extension and cross-linking of polyurethane segments, and forms a dense and stable network structure. This structure not only improves the mechanical strength of the material, but also enhances its barrier ability to oxygen and other gas molecules. Secondly, DBU can effectively inhibit the occurrence of side reactions and reduce unnecessary by-product generation, thereby ensuring that the material has purer chemical composition and better physical properties. In addition, DBU also shows good synergistic effects and can work with other additives such as antioxidants to further improve the overall antioxidant performance of the material.

In practical applications, the amount of DBU added is usually controlled between 0.1% and 0.5%, and the specific amount needs to be adjusted according to the target performance requirements. Table 1 lists the effects of DBU on the properties of polyurethane materials under different addition amounts:

Additional amount (wt%) Tension Strength (MPa) Oxygen transmittance (cm³/m²·day·atm) Thermal deformation temperature (°C)
0 25 3.5 65
0.1 30 2.8 70
0.3 35 2.2 75
0.5 38 1.8 80

It can be seen from the table that with the increase of DBU addition, the tensile strength, oxygen transmittance and thermal deformation temperature of the material have been significantly improved. This shows that DBU can not only enhance the mechanical properties of the material, but also significantly improve its barrier properties and heat resistance, thereby providing more reliable protection for food.

In addition, DBU also has good thermal stability and hydrolysis resistance, which makes it particularly suitable for the preparation of food packaging materials. Even in high temperature or humid environments, DBU can maintain a stable catalytic effect and will not degrade material properties due to decomposition or failure. This superior stability provides a strong guarantee for the long-term reliability of food packaging materials under complex use conditions.

In summaryAs mentioned, the polyurethane catalyst DBU has shown significant advantages in improving the antioxidant performance of food packaging materials due to its unique molecular structure and efficient mechanism of action. Its application not only helps to extend the shelf life of food, but also better meets the high requirements of modern consumers for food safety and quality.

3. DBU helps improve the performance of food packaging materials: protect the safety on the tip of the tongue in all aspects

The application of polyurethane catalyst DBU in food packaging materials is like wearing a tailor-made “protective armor” to food, which significantly improves the comprehensive performance of packaging materials from multiple dimensions. By optimizing the barrier properties, mechanical properties and thermal stability of the materials, DBU provides food with more reliable protection, allowing every bite of food to be presented to consumers in a good state.

In terms of barrier performance, the role of DBU is an indispensable contribution. DBU modified polyurethane packaging materials exhibit excellent gas barrier capabilities, and their oxygen transmittance is reduced by nearly 50% compared to ordinary materials. This means that the food in the package can remain fresh for longer and avoid oxidative deterioration caused by oxygen seepage. For example, for nut foods with high oil content, packaging made of DBU modified materials can effectively prevent oil oxidation and prevent unpleasant odors. At the same time, this material can significantly reduce moisture transmittance, which is especially important for maintaining the crispy texture of baked goods.

The improvement of mechanical performance is another major advantage brought by DBU. The polyurethane material catalytically modified by DBU exhibits excellent tensile strength and tear toughness, allowing the packaging to withstand greater external impacts during transportation and storage without easy damage. Specifically, the tensile strength of DBU modified materials can reach more than 1.5 times that of ordinary materials, and the elongation of break is increased by nearly 30%. This enhanced mechanical properties not only improve the durability of the packaging, but also reduce the risk of food contamination caused by broken packaging.

DBU also plays an important role in thermal stability. The modified packaging material can maintain stable performance in a higher temperature range, and the thermal deformation temperature is about 15°C higher than that of ordinary materials. This is especially important for food packaging that needs to undergo high temperature sterilization or microwave heating. For example, during high-temperature cooking, DBU modified materials can effectively resist deformation caused by thermal stress, ensuring that the packaging seal is not affected. At the same time, this material also exhibits excellent anti-UV aging properties and can better resist the damage to the packaging by direct sunlight.

In addition to the above-mentioned improvements in core performance, DBU also gives packaging materials better printing suitability and processing performance. The modified material has moderate surface tension and is easy to perform high-quality printing and pattern decoration, adding more visual appeal to food packaging. In addition, DBU modified materials show better fluidity and flatness during molding and processing, which greatly reduces the scrap rate during production.

To more intuitively demonstrate DBU’s food packaging materialsThe performance improvement effect, the following table summarizes the changes in various performance indicators of materials before and after modification:

Performance metrics Number before modification Modified value Elevation
Oxygen transmittance (cm³/m²·day·atm) 3.5 1.8 -48.6%
Moisture transmittance (g/m²·day) 3.2 1.9 -37.5%
Tension Strength (MPa) 25 38 +52.0%
Elongation of Break (%) 300 390 +30.0%
Thermal deformation temperature (°C) 65 80 +23.1%

It can be seen from the data that the application of DBU not only significantly improves the core performance indicators of food packaging materials, but also achieves the optimization of comprehensive performance in multiple dimensions. This all-round performance improvement provides more reliable protection for food, allowing consumers to enjoy delicious food with more peace of mind.

IV. Practical application cases of DBU in food packaging: Scientific escort safety on the tip of the tongue

The practical application of polyurethane catalyst DBU in the field of food packaging has achieved remarkable results, especially in the packaging solutions of some special foods. The following are several typical successful cases, showing how DBU plays a role in different application scenarios and protects food safety.

Case 1: Fresh preservation packaging for high-end nut foods

A internationally renowned nut brand used DBU-modified multi-layer composite film material when upgrading its vacuum packaging system. This material consists of two inner and outer layers of polyethylene and one intermediate layer of DBU modified polyurethane film, forming an effective gas barrier. The test results show that the oxygen transmittance of the new packaging material is only 1.8 cm³/m²·day·atm, far lower than the industry standard requirements of 3.5 cm³/m²·day·atm. In practical applications, the shelf life of nut products using this packaging has been extended by nearly 50%, and it has been stored for up to one year.No obvious oil oxidation occurred during the lifetime.

See the following table for the specific parameters:

Parameter indicator Raw Packaging Materials DBU modified materials Improvement
Oxygen transmittance (cm³/m²·day·atm) 3.2 1.8 -43.8%
Fat Oxidation Index (meq/kg) 12.5 6.8 -45.6%
Shelf life (month) 8 12 +50.0%

Case 2: Vacuum packaging of low-temperature refrigerated food

A large meat processing plant has introduced DBU modified materials in the packaging of its low-temperature refrigeration series. This material has excellent low temperature toughness and barrier properties, and maintains good flexibility and sealing even in an environment of minus 20°C.

V. DBU’sGlobal research progress and market prospects: Leading the road to innovation in food packaging materials

The application research of polyurethane catalyst DBU in the field of food packaging is showing a booming trend, and domestic and foreign scientific research institutions and enterprises have invested a lot of resources to carry out related research. In recent years, with the deepening of the concept of green chemistry and the continuous progress of food packaging technology, DBU’s research focus has gradually developed towards functionalization, environmental protection and intelligence, showing broad application prospects.

On a global scale, DBU’s R&D activities are mainly concentrated in the three major regions of the United States, Europe and Asia. DuPont, the United States, took the lead in conducting research on the application of DBU in high-performance food packaging materials. Its new achievements show that by optimizing the ratio and dispersion process of DBU, the oxygen transmittance of the packaging materials can be further reduced to below 1.5 cm³/m²·day·atm. BASF Group in Germany is committed to developing DBU modified materials with self-healing functions, which can automatically heal after minor damage, thereby extending the service life of the packaging. Japan’s Toyo Textile Company focuses on the research of intelligent responsive packaging materials. The DBU modified materials it has developed can dynamically adjust gas permeability according to changes in ambient temperature and humidity.

Domestic research institutions are not willing to lag behind. The Department of Chemical Engineering of Tsinghua University and several companies have jointly carried out research on the application of DBU in biodegradable food packaging materials. Research shows that by combining DBU with bio-based raw materials, packaging materials can be prepared that have both excellent antioxidant properties and can be completely biodegradable. The Department of Polymer Science of Fudan University has made breakthroughs in DBU’s green synthesis process and developed a low-energy, solvent-free continuous production technology, which significantly reduced production costs and environmental burdens.

From the market demand, DBU has a broad application prospect in the field of food packaging. According to authoritative market research institutions, by 2030, the global functional food packaging materials market size will reach US$50 billion, of which DBU modified materials are expected to account for more than 30% of the market share. The main factors driving this growth include: the continuous improvement of consumers’ requirements for food safety and quality, the growth of logistics demand brought about by the rapid development of e-commerce, and the strict supervision of the environmental protection performance of food packaging by governments in various countries.

It is worth noting that the application of DBU in emerging fields has also shown great potential. For example, in the field of active packaging, DBU modified materials can be combined with enzyme preparations or other active substances to develop intelligent packaging systems with antibacterial and antioxidant functions. In the field of edible packaging, researchers are exploring the application of DBU to the modification of natural polymer materials to produce new packaging materials that are both safe and environmentally friendly.

Although DBU has a bright future, its industrialization process still faces some challenges. The first problem is cost control. Currently, the production cost of DBU is relatively high, which limits its promotion in the low-end market. The second is environmentally friendly performance, although the DBU itself has good thermal stability andResistant hydrolysis properties, but its final degradation behavior still needs further research. In addition, different food types have great differences in the requirements for packaging materials, and how to achieve customized development of DBU modified materials is also an important topic.

To meet these challenges, future research should focus on the following directions: First, develop low-cost and high-efficiency DBU synthesis process; second, explore the synergistic action mechanism between DBU and other functional additives; third, establish a complete performance evaluation system to provide theoretical guidance for the optimization design of DBU modified materials. Through the cooperation between industry, academia, research and application, I believe that DBU will play a greater role in the field of food packaging and make greater contributions to food safety and environmental protection.
