摘要
纳米SiO2由于具有无味、无毒、无污染等特性,因而被广泛用作无机纳米填料。纳米SiO2极易团聚,从而限制了它的广泛应用。但纳米SiO2表面富含大量的硅羟基,可对其进行表面改性。纳米SiO2表面改性的方法较多,主要有表面物理改性和表面化学改性两种,其中表面化学改性中又以聚合物改性的效果最好。本文综述了国内外利用不同的聚合物——亲水性、疏水性和两亲性聚合物对纳米SiO2表面的化学改性,并对其应用进行了分析,展望了其发展前景。
Nano-SiO2 is widely used as nano-fillers due to its odorless,nontoxic,nonpolluting and other characteristics. The applications of nano-SiO2 particles are restricted for their easily aggregation properties.But nano-SiO2surfaces contain rich silanol groups,it can be modified.The physical and chemical surface modifications are two main methods in many methods for nano-SiO2 surface modification.Polymer modification is better method in chemical surface modification. Chemical modifications of nano-SiO2 surface by hydrophilic,hydrophobic,and amphiphilic polymers at home and abroad have been reviewed,their applications have been analyzed,and their promising development has been predicted.
