Application of 2-methylimidazole in high-strength fiber composite materialsCurrent situation

The application of 2-methylimidazole in high-strength fiber composite materials has made significant progress, especially in the following aspects:

  1. Epoxy resin curing agent

    Epoxy resin is one of the commonly used matrix materials in high-strength fiber composite materials. Its excellent mechanical properties and chemical resistance make it widely used in aerospace, automobile manufacturing and other fields. However, traditional epoxy resin curing agents such as amine curing agents have problems such as high curing temperature and long curing time, which limits their application in certain special occasions. As a highly efficient epoxy resin curing agent, 2-methylimidazole can cure quickly at lower temperatures, and the cured resin has higher cross-linking density and better mechanical properties.

    According to literature reports, the reaction mechanism of 2-methylimidazole and epoxy resin is mainly through the ring-opening addition reaction between nitrogen atoms on the imidazole ring and epoxy groups, forming a stable covalent bond. This reaction not only improves the crosslinking density of the resin, but also enhances the heat and fatigue resistance of the material. Studies have shown that after the addition of 2-methylimidazole, the glass transition temperature (Tg) of the epoxy resin can be increased from the original 120°C to above 150°C, and the tensile strength and modulus are also increased by 20% and 15%, respectively. %.

  2. Toughening Agent

    Although high-strength fiber composites have excellent mechanical properties, they are highly brittle and prone to fracture when impacted. Therefore, how to improve the toughness of materials has become an important research direction. As a toughening agent, 2-methylimidazole can effectively improve the toughness of composite materials and reduce the possibility of crack propagation.

    The toughening mechanism of 2-methylimidazole is mainly related to its molecular structure. Because its molecules contain flexible segments and polar groups, it can form a micro-phase separation structure inside the material, which plays a role in stress dispersion. At the same time, 2-methylimidazole can also undergo chemical bonding to the fiber surface, enhancing the interface bonding force between the fiber and the matrix, thereby improving the overall toughness of the material. Experimental results show that after the addition of 2-methylimidazole, the impact strength of the composite material can be increased by more than 30%, and the fracture toughness has also been significantly improved.

  3. Anti-bacterial agent

    In some special application occasions, such as medical devices, food packaging and other fields, composite materials need to have certain antibacterial properties. As a natural antibacterial agent, 2-methylimidazole can inhibit the growth and reproduction of bacteria, fungi and other microorganisms to a certain extent and extend the service life of the material.

    In high-strength fiber composites, the interface bonding force between the fiber and the matrix has a crucial impact on the overall performance of the material. 2-methylimidazole can chemically bond to the fiber surface to form a firm interface layer, which enhances the bonding force between the fiber and the matrix. Specifically, nitrogen atoms in the 2-methylimidazole molecule can undergo hydrogen bonding with hydroxyl groups or other active groups on the surface of the fiber to form stable chemical bonds. This enhancement of interface bonding not only improves the mechanical properties of the material, but also reduces the possibility of crack propagation, thereby improving the durability of the material.

  3. Stress Dispersion and Toughness Improvement

    2-Methylimidazole molecules contain flexible segments and polar groups, which can form micro-phase separation structures inside the material and play a role in stress dispersion. When the composite material is subjected to external forces, these micro-phase separation structures can effectively disperse stress and prevent cracks from occurring and spreading. In addition, 2-methylimidazole can also work synergistically with other components in the matrix to further improve the toughness of the material. Experimental results show that after the addition of 2-methylimidazole, the impact strength and fracture toughness of the composite material were significantly improved.

    The nitrogen atoms in the 2-methylimidazole molecule can interact with proteins on the microbial cell membrane, destroying the integrity of the cell membrane and leading to the death of microbial organisms. This antibacterial mechanism allows 2-methylimidazole to have certain antibacterial properties in composite materials and can inhibit the growth and reproduction of bacteria, fungi and other microorganisms to a certain extent. Studies have shown that 2-methylimidazole has a good inhibitory effect on common pathogens such as E. coli and Staphylococcus aureus, and the low inhibitory concentration (MIC) is only about 100 ppm.

  5. Enhanced heat resistance

    The aromatic ring and nitrogen atoms in the 2-methylimidazole molecule can form stable chemical bonds at high temperatures to prevent thermal degradation of the material. In addition, 2-methylimidazole can also work synergistically with other components in the matrix to further improve the heat resistance of the material. Experimental results show that after the addition of 2-methylimidazole, the thermal decomposition temperature of the composite can be increased from the original 300°C to above 350°C, and the heat resistance is significantly improved.

Market demand for self-cleaning materials

As the urbanization process accelerates, the pollution problem on the surface of buildings is becoming increasingly serious. Contaminants such as dust, oil, mold, etc. not only affect the appearance of the building, but may also cause damage to the building structure. Traditional cleaning methods rely on manual cleaning or the use of chemical cleaners, which is time-consuming and labor-intensive and can also cause pollution to the environment. Therefore, the development of building materials with self-cleaning functions has become an urgent need in the construction industry.

The core of self-cleaning materials is that their surface can automatically remove contaminants attached to them through physical or chemical action. This material not only reduces the frequency of cleaning and reduces maintenance costs, but also extends the service life of the building and improves the overall quality of the building. 2-methylimidazole, as an efficient self-cleaning functional additive, came into being in this context.

The working principle of 2-methylimidazole

The reason why 2-methylimidazole can impart self-cleaning function to building materials is mainly due to its special molecular structure and chemical properties. When 2-methylimidazole is introduced into the building material, it forms a superhydrophobic coating on the surface of the material. This coating has extremely low surface energy, so that the water droplets appear nearly spherical on their surface, with contact angles up to 150° or above. In this way, water droplets can quickly roll off under the action of gravity or wind, taking away dust and dirt from the surface, thereby achieving a self-cleaning effect.

In addition, 2-methylimidazole also has certain antibacterial properties. Studies have shown that 2-methylimidazole can inhibit the growth and reproduction of bacteria, mold and other microorganisms by interfering with the integrity of microbial cell membranes. This characteristic allows building materials containing 2-methylimidazole to not only keep clean, but also effectively prevent microbial erosion and further extend the building.service life.

2-The application form of methylimidazole in building materials

2-methylimidazole can be used in building materials in a variety of ways, depending on the type of material and the use scenario. The following are several common application forms:

1. Paints and paints

Coating is one of the commonly used surface treatment materials in building materials. By adding 2-methylimidazole to the coating, its self-cleaning properties can be significantly improved. 2-methylimidazole reacts with the film-forming substance in the coating to form a stable superhydrophobic coating, making the surface of the coating less likely to absorb dust and dirt. At the same time, 2-methylimidazole can also enhance the weather resistance of the coating, so that it can still maintain good performance in harsh environments.

Abrasion resistance 30% increase
Weather Resistance Increase by 20%
Anti-bacterial properties Inhibit 99.9% of bacterial and mold growth
Scope of application Exterior wall paint, roof paint, interior decorative paint, etc.

2. Glass and Ceramics

Glass and ceramics are commonly used transparent or translucent materials in buildings and are easily affected by pollutants such as dust and oil. 2-methylimidazole can be prepared on the glass and ceramic surfaces by electroless coating technology or sol-gel method to form a superhydrophobic coating. This coating can not only effectively prevent contaminants from adhesion, but also improve the material’s ultraviolet resistance and acid-base corrosion resistance, and extend its service life.

Parameters Description
Light transmittance >90%
Contact Angle >160°
UV resistance Advance by 50%
Acid and alkali corrosion resistance Advance by 40%
Scope of application Building glass, curtain wall glass, ceramic tiles, etc.

3. Concrete and Stone

Concrete and stone are one of the common materials in building structures, but due to their porous and rough surfaces, they tend to absorb dust and pollutants. 2-methylimidazole can be applied to concrete and stone surfaces by immersion or spraying to form a dense protective layer. This protective layer not only prevents pollutants from penetrating, but also improves the material’s weathering resistance and freeze-thaw resistance and extends its service life.

Traditional materials such as ITO are prone to cracks when bending or folding, resulting in reduced conductivity and even complete failure. Due to the flexibility and self-assembly properties of the molecular chain, 2-methylimidazolyl materials can maintain good conductivity during repeated bending and folding without obvious performance attenuation.

Secondly, the 2-methylimidazolyl material has a higher transparency. The transparent conductive layer must not only have good conductivity, but also ensure a high light transmittance to ensure that the display effect of the display screen is not affected. Studies have shown that the light transmittance of 2-methylimidazolyl material can reach more than 90%, which is close to the transparency of glass, which makes it have great application potential in flexible display screens.

In addition, the preparation process of 2-methylimidazolyl materials is relatively simple and has a low cost. Traditional transparent conductive materials such as ITO need to be deposited at high temperatures, the equipment is complex and energy consumption is high. 2-methylimidazolyl materials can be prepared through low-cost processes such as solution method or inkjet printing, which greatly reduces production costs and improves production efficiency.

After

, the 2-methylimidazolyl material has good environmental friendliness. Traditional materials such as ITO contain heavy metal elements, which are harmful to the environment and human health. 2-methylimidazole is an organic small molecule, non-toxic and harmless, meets the requirements of green and environmental protection, and is suitable for future sustainable development needs.

Method for preparing 2-methylimidazolyl transparent conductive layer

The preparation methods of 2-methylimidazolyl transparent conductive layer are various, mainly including solution method, inkjet printing method, spin coating method and self-assembly method. Different preparation methods have their own advantages and disadvantages and are suitable for different application scenarios. Below we will introduce several common preparation methods and their characteristics in detail.

1. Solution method

The solution method is one of the commonly used methods for preparing 2-methylimidazolyl transparent conductive layer. This method forms a transparent conductive layer by dissolving 2-methylimidazole in a suitable solvent and then coating it on the substrate after drying and curing. The advantage of the solution method is that it is simple to operate, low cost, and is suitable for large-scale production. However, the disadvantage of the solution method is that the film formation uniformity is poor, and the problem of uneven thickness is prone to occur, which affects the conductivity.

2. Inkjet printing method

Inkjet printing method is an emerging method for preparing 2-methylimidazolyl transparent conductive layer. This method uses an inkjet printer to print ink containing 2-methylimidazole directly onto the substrate to form a patterned transparent conductive layer. The advantage of inkjet printing is that it can achieve high-precision patterning and is suitable for complex circuit designs. In addition, the inkjet printing method can also be combined with other functional materials to prepare a multifunctional transparent conductive layer. However, the disadvantage of inkjet printing is that it is slow in preparation and is not suitable for mass production.

3. Spin coating method

Spin coating is a classic film preparation method and is widely used in the fields of semiconductors and optoelectronics. This method uses centrifugal force to uniformly distribute the solution and form a thin film by dropwise addition of a solution containing 2-methylimidazole on a rotating substrate. The advantage of spin coating is film formationGood uniformity and controllable thickness, suitable for laboratory research and small batch production. However, the disadvantage of spin coating is that the preparation area is limited and it is not suitable for the preparation of large-area transparent conductive layers.

4. Self-assembly method

The self-assembly method is an innovative method for the preparation of 2-methylimidazolyl transparent conductive layer. This method uses weak interactions between 2-methylimidazole molecules (such as hydrogen bonding, ?-? stacking, etc.) to make it spontaneously form ordered nanostructures on the substrate surface. The advantage of the self-assembly method is that it is possible to prepare a transparent conductive layer with excellent conductivity and high transparency, and the microstructure and performance of the material can also be adjusted by regulating the self-assembly conditions. However, the disadvantage of the self-assembly method is that the preparation process is relatively complex and requires precise control of experimental conditions.
