Silica aerogels are known as the mesoporous material with the high porosity and the low thermal conductivity. Silica aerogels were prepared with IPA, HCl, TMCS and water glass via the sol-gel method. In this study, the amount of TMCS used in the preparation of silica aerogels was controlled to improve the dispersivity of silica aerogels in polyurethane raw materials. The particle size and structure of Silica aerogels prepared by controlling the amount of TMCS were analyzed by FE-SEM and EDS. And the dispersion stability of silica aerogels in polyurethane solution were observed over time. |
