2月 15th, 2025 News

Introduction

With the acceleration of global industrialization and urbanization, air quality issues have attracted increasing attention. Air pollution not only poses a threat to human health, but also causes serious damage to the ecological environment. Among many air purification technologies, the application of catalysts is highly favored for their high efficiency and environmental protection. As a new material, low-density sponge catalyst (SMP, Sponge Matrix Catalyst) has shown significant advantages in improving the air quality of the working environment in recent years. This article will discuss in detail the principles, applications, product parameters and their performance in actual working environment, and summarize experience in combination with domestic and foreign literature.

Air quality issues are a global challenge, especially in industrial production and office environments, the emissions of harmful gases such as volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), etc., seriously affect the emissions of these gases, such as volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), etc., which seriously affect the emissions of these gases, such as volatile organic compounds (VOCs), and nitrogen oxides (NOx), and sulfur dioxide (SO2), which have a serious impact on the emissions of these gases. The health and productivity of employees. Long-term exposure to these pollutants can lead to respiratory diseases, cardiovascular diseases and even cancer. Therefore, how to effectively purify the air and create a healthy working environment has become the focus of common concern for enterprises and governments.

SMP catalysts, as an efficient air purification material, have unique physical and chemical properties, can catalyze the decomposition of harmful gases at lower temperatures and reduce pollutant emissions. Its porous structure and high specific surface area allow it to be in full contact with gas molecules, thereby improving catalytic efficiency. In addition, SMP catalysts also have good mechanical strength and durability, and are suitable for various complex industrial environments.

This article will discuss from the following aspects: First, introduce the basic principles and working mechanism of SMP catalysts; second, analyze the product parameters of SMP catalysts in detail and their performance in different application scenarios; again, combine with domestic and foreign Literature discusses the application effect of SMP catalyst in actual working environment; then, summarizes the advantages and future development direction of SMP catalysts, and provides reference for research and practice in related fields.

The basic principles of low-density sponge catalyst (SMP)

Low density sponge catalyst (SMP) is a porous material-based catalyst whose unique physical and chemical properties make it outstanding in the field of air purification. The core of SMP catalyst lies in the synergistic effect of its porous structure and active ingredients, which can efficiently catalyze and decompose harmful gases at lower temperatures, thereby achieving the purpose of purifying air.

1. Porous structure and high specific surface area

The porous structure of SMP catalysts is the key to its efficient performance. This structure is formed through a special manufacturing process, usually using foaming or sintering technology, which causes a large number of tiny pores and channels to form inside the catalyst material. These channels not only increase the specific surface area of ??the catalyst, but also provide more contact points for the gas molecules, thereby improving the efficiency of the catalytic reaction.

ResearchIt has been shown that the specific surface area of ??SMP catalysts can reach 500-1000 m²/g, which is much higher than that of traditional catalysts. High specific surface area means more active sites, which can adsorb more pollutant molecules, and promote the occurrence of catalytic reactions. According to research by the U.S. Environmental Protection Agency (EPA), the specific surface area of ??a porous catalyst is positively correlated with its catalytic efficiency. The larger the specific surface area, the higher the catalytic efficiency (EPA, 2018).

2. Active ingredients and catalytic mechanism

The active ingredients of SMP catalysts usually include noble metals (such as platinum, palladium, rhodium) or transition metal oxides (such as manganese, iron, copper). These active ingredients are introduced into the porous matrix by loading or doping, forming a composite material with high catalytic activity. The selection and distribution of active ingredients have an important influence on the performance of the catalyst.

Take the platinum-based SMP catalyst as an example, platinum atoms can effectively adsorb oxygen molecules and activate them into reactive oxygen species (O??, O?, OH?, etc.). These reactive oxygen species then undergo a redox reaction with harmful gases (such as VOCs, NOx, SO?) and decompose them into harmless products (such as CO?, H?O, N?). This process is called “oxidation catalysis” and is one of the main mechanisms for SMP catalysts to purify air.

In addition to oxidation catalysis, SMP catalysts can also treat nitrogen oxides (NOx) through reduction catalysis. For example, under a reducing atmosphere, the metal active sites in the SMP catalyst can adsorb and activate NOx molecules, causing them to react with reducing agents (such as NH?, CO) to produce nitrogen and water. This process not only effectively removes NOx, but also reduces the generation of secondary pollutants.

3. Temperature adaptability and reaction conditions

A significant advantage of SMP catalysts is their wide temperature adaptability. Traditional catalysts usually require high temperature conditions to perform well, while SMP catalysts can achieve efficient catalytic reactions at lower temperatures (150-400°C). This makes SMP catalysts particularly suitable for use in some industrial scenarios that cannot withstand high temperatures, such as indoor air purification, automobile exhaust treatment, etc.

Study shows that the low-temperature activity of SMP catalysts is mainly due to the synergistic effect of its porous structure and active ingredients. The porous structure not only increases the diffusion path of gas molecules, but also provides more contact opportunities for the active ingredients, thereby reducing the activation energy of the reaction. In addition, the metal active sites in the SMP catalyst can maintain high catalytic activity at lower temperatures, ensuring their stable performance under different temperature conditions.

4. Mechanical strength and durability

Another important feature of SMP catalyst is its excellent mechanical strength and durability. Due to the spongy porous structure, SMP catalyst has good elasticity and compressive resistance, and can be used for a long time in complex industrial environments without easy damage. In addition, SMPThe durability of the catalyst is also reflected in its ability to resist poisoning to pollutants. Studies have shown that the active ingredients in SMP catalysts can effectively resist the toxicity of harmful substances such as sulfides and chlorides, and maintain long-term and stable catalytic performance.

To sum up, SMP catalysts can show excellent performance in the air purification process through their unique porous structure, active ingredients and low temperature adaptability. Its efficient, stable and durable characteristics make it an ideal choice for improving the air quality in the working environment.

Low-density sponge catalyst SMP provides better protection technology for smart wearable devices

2月 15th, 2025 News

Application of low-density sponge catalyst SMP in smart wearable devices

With the rapid development of technology, smart wearable devices such as smart watches, health bracelets, smart glasses, etc. have become an important part of people’s daily life. These devices not only provide convenient functions, but also play an important role in health management, exercise monitoring, communications, etc. However, the lightweight and miniaturized design of smart wearable devices also present new challenges, especially in terms of protective performance. How to provide sufficient protection while ensuring the equipment is lightweight has become the focus of manufacturers and researchers.

Shape Memory Polymer, a low-density sponge catalyst, has shown great potential in the field of protection of smart wearable devices in recent years. SMP materials have unique shape memory characteristics and can return to preset shapes when subjected to external stimuli (such as temperature, humidity, mechanical stress, etc.). This characteristic allows SMP materials to effectively absorb energy when impacted or collided, reducing damage to the internal components of the equipment. In addition, the low density properties of SMP materials allow it to provide excellent buffering and protection without affecting the overall weight of the device.

This article will discuss in detail the application of low-density sponge catalyst SMP in smart wearable devices, including its working principle, technical advantages, product parameters, application scenarios and future development trends. By citing relevant domestic and foreign literature, this article will provide readers with a comprehensive and in-depth understanding, helping manufacturers and R&D personnel better use SMP materials to improve the protection performance of smart wearable devices.

1. Working principle of low-density sponge catalyst SMP

Low density sponge catalyst SMP is a shape memory polymer-based material whose core characteristic is that it can undergo shape changes under specific conditions and restore to its original shape after the external stimuli disappears. This property of SMP materials stems from the unique design of their molecular structure, usually consisting of crosslinked polymer networks that contain reversible physical or chemical bonds. When the material is subjected to external stimuli (such as temperature rise, mechanical stress, etc.), these bonds will break or reorganize, causing the shape of the material to change; and after the stimulus disappears, the material will spontaneously return to its original shape through thermodynamic drive.

The shape memory effect of SMP materials can be achieved through the following mechanisms:

  • Thermal shape memory effect: This is a common shape memory mechanism. SMP materials can be shaped at low temperatures and then restore to their original shape when heated above the glass transition temperature (Tg). . This mechanism relies on the glass transition temperature of the material, and usually requires precise control of the temperature to ensure the effect of shape recovery.

  • Wet shape memory effect: Some SMP materials expand or shrink after absorbing water, thereby changing their shape. This mechanism is suitable for applications in humid environments, such as providing additional protection when sweat or other liquids are in contact.

  • Electrogenic Shape Memory Effect: By applying an electric field or current, SMP materials can undergo shape changes in a short period of time. This mechanism is suitable for application scenarios that require rapid response, such as starting the protection mechanism immediately upon impact.

  • Magnetic Shape Memory Effect: Some SMP materials will undergo shape changes under the action of magnetic fields. This mechanism is suitable for application scenarios that require remote control.

In smart wearable devices, the shape memory effect of SMP materials is mainly used to absorb and disperse external impact energy. When the device is hit or dropped, the SMP material will deform instantly, absorbing impact forces and converting them into thermal energy or other forms of energy, thereby reducing the impact on the components inside the device. Subsequently, the SMP material will return to its original shape in a short period of time to ensure the normal operation of the equipment. This adaptive protection mechanism not only improves the durability of the device, but also extends its service life.

2. Technical advantages of low-density sponge catalyst SMP

Compared with traditional protective materials, the low-density sponge catalyst SMP has many significant technical advantages in smart wearable devices. Here are the main advantages of SMP materials:

Technical Advantages Detailed description
Lightweight SMP materials have lower density, usually between 0.1-0.5 g/cm³, much lower than conventional foam materials (such as EVA foam). This allows SMP materials to provide excellent buffering and protection without increasing the weight of the equipment.
High energy absorption capacity SMP materials have high energy absorption efficiency, can quickly deform and absorb a large amount of energy when impacted. Research shows that the energy absorption rate of SMP materials can reach more than twice that of traditional foam materials, effectively reducing the impact of impact on the internal components of the equipment.
Self-healing Some SMP materials have self-healing properties, i.e., after minor damage, they can be restored to their original state by heating or otherwise. This characteristic allows SMP materials to remain good during long-term useGood protective performance reduces maintenance costs.
High customization The shape memory effect of SMP materials can be precisely controlled by adjusting the material’s formulation and processing technology. Manufacturers can customize SMP materials with specific shape memory characteristics according to the needs of different smart wearable devices to meet different protection requirements.
Environmentally friendly The production process of SMP materials is relatively simple and does not require the use of a large number of harmful chemicals. In addition, SMP materials can be recycled and reused after their service life, which is in line with modern environmental protection concepts.
Strong weather resistance SMP materials have excellent weather resistance and can maintain stable performance under extreme temperature, humidity and ultraviolet rays. This is especially important for smart wearable devices for outdoor use, ensuring the reliability and durability of the device under various environmental conditions.

3. Product parameters of low-density sponge catalyst SMP

From the table above, the density of SMP materials is significantly lower than that of traditional EVA foams, but they perform well in terms of energy absorption. In particular, SMP-100 and SMP-200 have their energy absorption rates of 85% and 78%, respectively, which is much higher than the 50% of EVA foam. In addition, the shape memory temperature range of SMP materials is wide and can adapt to different usage environments. The self-repair time varies according to the type of material, but overall, the repair can be completed in a short time.

This mechanism can trigger the shape changes of the material through lighting and is suitable for application scenarios where remote control or automated operations are required.

5.4 Promote intelligent integration

The smart wearable devices of the future will not be just a simple protection tool, but a smart terminal with multiple functions. The shape memory effect of SMP materials can be combined with electronic components such as sensors and processors to achieve intelligent protection and adaptive adjustment. For example, when the device detects an imminent collision, the SMP material can quickly activate the protection mechanism, absorb impact energy in advance, and further improve the safety of the device.
