Direct Formation of Aerogels by Sol−Gel Polymerizations of Alkoxysilanes in Supercritical Carbon Dioxide
Source abstract
Abstract
We report the first sol−gel polymerization of alkoxysilane monomers in supercritical carbon dioxide (SCCD) as the polymerization solvent. Monolithic silica and silsesquioxane gels were formed in SCCD by the nonaqueous polymerization of tetramethoxysilane and 1,4-bis(triethoxysilyl)benzene, respectively, with formic acid (99%). The gels were dried to give high surface area, mesoporous aerogels by simply venting carbon dioxide from the autoclave.
