With the continuous development of technology, people's requirements for materials are also increasing. Surface modification technology is widely used because it can improve the surface properties of materials.

By using physical, chemical, mechanical and other methods to treat the surface or interface of powder materials, the chemical properties of the powder material surface are purposefully modified, such as gloss, coloring power, covering power, color retention, weather resistance and other properties, in order to improve product performance and develop various new products. Among them, organosilicon has become one of the preferred surface modification technologies.

For example, inorganic mineral fillers play an important role in the polymer material industry such as plastics, rubber, adhesives, and polymer based composite materials. However, due to the different surface or interface properties between inorganic powder fillers and the matrix, i.e. organic polymers, their compatibility is poor, making it difficult to uniformly disperse in the matrix.

Direct or excessive filling often leads to a decrease in certain mechanical properties and brittleness of the material. Therefore, it is necessary to modify the surface of inorganic powder fillers to improve their physical and chemical properties, enhance their compatibility with the matrix, such as organic polymers or resins, and their dispersibility in the organic matrix, in order to improve the mechanical strength and overall performance of the material.
