Recently, as a key additive in the polymer material field, silane coupling agents have set off an application boom in various industries such as composite materials and chemical production with their unique interface modification capabilities, becoming the core support for improving material performance. This special substance with both inorganic and organic functional groups is promoting the upgrading of related industries through innovative technologies. The molecular structure of silane coupling agents contains two types of core functional groups: one can form chemical bonds with inorganic fillers, and the other can react with organic polymer materials or achieve good compatibility, just like a "molecular bridge" built between inorganic and organic substances. Its mechanism of action includes various theories such as chemical bonding and deformable layer. By improving interface adhesion, it effectively solves the pain points such as uneven filler dispersion and difference in thermal shrinkage rate in traditional composite materials, and significantly improves the key properties of materials such as mechanical strength and hydrolysis resistance. In terms of synthesis process, silane coupling agents achieve functional customization by accurately introducing hydrolyzable groups and organic functional groups. Common groups such as alkoxy and acetoxy endow them with diverse adaptability. At present, such additives have been widely used in the production of plastics, rubber, coatings and other products, and their applications in emerging fields such as new energy and electronic materials are also continuously expanding, providing more possibilities for material innovation. As an important category of surface modifiers, the technological iteration and application expansion of silane coupling agents are helping related industries transform towards high performance and green environmental protection. In the future, with the continuous breakthrough of synthesis technology, their application potential in more subdivided fields will be further released.
