Abstract
Aerogel materials, aerogel composites, and the like may be improved by the addition of opacifiers to reduce the radiative component of heat transfer. Such aerogel materials, aerogel composites, and the like may also be treated to impart or improve hydrophobicity. Such aerogel materials and methods of manufacturing the same are described.
Claims11
A method comprising:
- (a) forming a silica gel mixture comprising silica gel and fillers;
- (b) combining the silica gel mixture with a reinforcing structure;
- and (c) drying the combined silica gel mixture to form a silica aerogel composition comprising a dried silica aerogel and the fillers;
- the fillers comprising (1) an opacifying compound embedded within the silica aerogel composition, (2) a hydrated filler, and (3) hydrophobic materials attached to a surface of the dried silica aerogel.
