乙烯基三甲氧基硅烷(VTMS)和六甲基二硅氮烷(HMDS)共改性气相二氧化硅,并以其为Pickering乳化剂,制备了水性乙烯基硅油乳液和含氢硅油Pickering乳液,肉眼观察乳液的储存稳定性,并拍照。
Fumed silica was first co-modified with vinyltrimethoxysilane (VTMS) and hexamethyl disilylamine (HMDS), then modified silica was further used as Pickering agent to prepare vinyl dimethicone emulsion and hydrogen dimethicone emulsion. The stability of the emulsions was observed with naked eyes and meanwhile photoed using a digital camera.
