摘要
采用几种常用硅烷偶联剂以及两种自制偶联剂,分别对硅溶胶中的纳米SiO2粒子进行表面改性,之后将纳米SiO2粒子分散到含氢硅油中得到改性后的含氢硅油。考察了几种偶联剂对纳米SiO2粒子表面改性及其在含氢硅油中分散效果的影响。
The nano-silica particles in the silica sol were modified by several commonly used and two self-made coupling agents respectively. Then the modified silica sol were dispersed in the hydrogensilicone oil. The effects of several cou- pling agents on the surface modification of nano-SiO2 particles and their dispersions in hydrogen silicone oil were investi- gated.
