Ambient pressure process for preparing aerogel thin films reliquified sols useful in preparing aerogel thin films
Abstract
A method for preparing aerogel thin films by an ambient-pressure, continuous process. The method of this invention obviates the use of an autoclave and is amenable to the formation of thin films by operations such as dip coating. The method is less energy intensive and less dangerous than conventional supercritical aerogel processing techniques.
