Method for preparing silica airgel and silica aerogels prepared thereby |
| abstract |
The present invention relates to a method for producing a silica airgel and to a silica airgel produced thereby. The method for preparing silica airgel according to the present invention comprises the steps of preparing a wet gel by a sol-gel method; Substituting a solvent of the wet gel using a ternary azeotropic mixing method and surface modifying the wet gel in which the solvent is substituted; It characterized in that it comprises an atmospheric pressure drying step of drying the surface-modified wet gel at normal pressure. Thereby, a method for producing a silica airgel having both high strength and high transparency and a silica airgel produced thereby are provided. |
