Ambient Dried Aerogels based on Alkyl Sulfide Bridged Polysilsesquioxanes
Aerogel is a low-density solid material that is produced by removing the liquid component from a conventional gel. Ambient dried aerogels utilize calculated levels of temperature and pressure using certain chemicals to remove the liquids from the aerogel. This technology is a method of preparation of low density, porous aerogels without the use of supercritical...
