nanosilica plays a key role in reinforcing plastics and composites. Due to the high specific surface area and good compatibility of nanosilica, it can effectively improve the mechanical properties of these materials. For example, adding nanosilica to polymers can increase the strength and hardness of the material, as well as its thermal stability and wear resistance. In addition, nanosilica can enhance the interfacial adhesion of composites and improve the impact resistance of materials.
