摘要
纳米二氧化硅是一种应用非常广泛的无机纳米材料,被用于涂料、塑料和橡胶等众多领域.但纳米二氧化硅的比表面能较高,很容易发生团聚现象,且与有机相相容性差,所以需要对纳米二氧化硅进行表面改性.将改性后的纳米二氧化硅应用到塑料、涂料和橡胶等材料中可以提高其综合性能.对近年来纳米二氧化硅的改性和应用进行了综述,并对纳米二氧化硅应用的前景进行了展望.
Nano-silica is a kind of widely used inorganic nanomaterials.It can be used in many fields such as coating,plastics and rubber.But nano-silica has a strong tendency to agglomerate due to its high surface energy.It has a poor compatibility with organic phase,therefore,the surface of nano-silica needs to be modified.The properties of the materials such as plastics,coating and rubber and so on can be improved by the use of the modified silica nanoparticles.The modification and application of nano-silica were reviewed in this paper.And the outlook of nano-silica was discussed.
