Next, we will explore the specific modification methods of BMIM in functional polymer materials and its impact on material properties.

Overview of functional polymer materials

Functional polymer materials refer to a new type of material that imparts specific functions to polymer materials through chemical or physical means. Compared with traditional polymer materials, functional polymer materials not only have excellent mechanical properties, but also exhibit special physical, chemical or biological functions in specific environments. In recent years, with the advancement of science and technology and the increase in market demand, functional polymer materials have been widely used in many fields, such as electronic devices, biomedicine, environmental protection, energy storage, etc.

For example, conductive polymer materials can generate electrical signals when currents pass through and are used to make flexible electronic devices; smart polymer materials can respond reversibly according to changes in the external environment (such as temperature, pH, light intensity, etc.), which is suitable for Drug release systems and sensors; while self-healing polymer materials can be repaired by themselves after being damaged, extending the service life of the material.

Modification technology plays a crucial role in the preparation of functional polymer materials. Modification refers to changing the structure or composition of a polymer material through physical or chemical means to improve its performance or impart new functions. Common modification methods include copolymerization, crosslinking, grafting, doping, etc. Among them, copolymerization is to copolymerize two or more monomers to form blocks or random copolymers with different functions; crosslinking is to form a three-dimensional network structure between linear polymer chains through chemical reactions to improve the material Strength and heat resistance; grafting is the introduction of branched or functional groups on the main chain of the polymer to enhance the hydrophilicity, hydrophobicity or biocompatibility of the material; doping is the uniform dispersion of other substances to the polymer In the substrate, the material is imparted with electrical conductivity, magnetic or optical properties.

The modified functional polymer materials not only significantly improve their performance, but also expand their application scope.

The synthesis method of IBMMI is relatively complex and is usually achieved by using multiple steps. Here are some common preparation methods:

  1. Synthesis of imidazole rings: First, the imidazole ring is formed by reacting 1,2-diaminoethane with formaldehyde. This process is the basis of IBMMI synthesis, and the presence of imidazole rings imparts excellent thermal and chemical stability to the compound.

  2. Introduction of substituents: Next, by reaction with isobutyl chloride and methyl iodide, isobutyl and methyl groups were introduced at the 1st and 2nd positions of the imidazole ring, respectively. This step is critical because it determines the final structure and performance of IBMMI.

  3. Purification and isolation: After that, the product was purified by column chromatography or recrystallization to obtain high purity IBMMI.

It should be noted that IBMMI synthesis involves a variety of hazardous chemicals, so safety specifications must be strictly observed in actual operation to ensure the safety of the experimental environment.

IBMMI in automotive parts

IBMMI is widely used in the automotive industry, covering almost all key components from the body to the engine. Below we will introduce the specific application of IBMMI in different automotive parts and its performance improvements.

1. Anti-corrosion coating

When the car is used, especially when driving in a humid or rainy environment, the car body is prone to corrosion, affecting its appearance and even leading to safety hazards. Although traditional anticorrosion coatings can delay corrosion to a certain extent, their protective effect will gradually weaken over time. As an efficient anticorrosion additive, IBMMI can significantly improve the corrosion resistance of the coating.

IBMMI’s imidazole ring structure has strong adsorption properties and can form a dense protective film on the metal surface, effectively preventing the invasion of moisture and oxygen. At the same time, the isobutyl and methyl groups in IBMMI molecules are hydrophobic, which further enhances theWaterproof properties of the coating. Studies have shown that in anticorrosion coatings containing IBMMI, the corrosion rate of metal surfaces can be reduced by more than 50%, and the service life of the coating is also greatly extended.

Waterproofing performance (contact angle) 80° 105°

2. Lutrient

The engine is the heart of the car, and the quality of the lubricant directly affects the engine’s operating efficiency and life. Although traditional mineral oil lubricants can provide a certain lubrication effect, their lubricating performance will rapidly decline in high temperature and high pressure environments, resulting in increased engine wear. As a high-performance extreme pressure anti-wear additive, IBMMI can significantly improve the performance of lubricants.

The imidazole ring in IBMMI molecules can form a stable lubricating film on the metal surface, and can maintain good lubricating effect even under extreme conditions. In addition, IBMMI also has excellent antioxidant properties and can effectively prevent lubricating oil from oxidizing and deteriorating at high temperatures. Experimental data show that the friction coefficient of lubricant with IBMMI was reduced by 30% at high temperatures and the wear of the engine was reduced by 40%.

With the popularity of electric vehicles, battery management systems and electronic control units have higher and higher requirements for conductive materials. Although traditional conductive materials such as copper and aluminum have good conductivity, they have a large weight and are prone to oxidation in certain special environments. As a new type of conductive additive, IBMMI can significantly improve the conductivity of composite materials while reducing the weight of the material.

Natural atoms in IBMMI molecules have strong electron affinity and can form conductive channels inside the material and enhance current transmission capability. In addition, the introduction of IBMMI can also improve the mechanical strength and heat resistance of the material, so that it still maintains good conductivity under high temperature environments. The experimental results show that the resistivity of the conductive composite material with IBMMI was reduced by 60%, and the conductivity was improved by 80%.
