| Abstract: | In this article, the progress of the drying technology at ambient pressure of silica aerogels and of theapplication of silica aerogel composite as the insulating material were reviewed. Several drying processes of silica aerogel such as improving the strength of gel network framework,adding chemical additives,surface modification,reducing
the capillary force and so on are summerized. In addition,the application of silica aerogels composites have been introduced as well. |
