Abstract:
In a method for producing a porous SiO2-xerogel starting solution containing a silicon compound is provided and organic monomers and an organically modified alkoxysilane are added to the starting solution. During gelification of the silicon compound, the organic monomers and the organically modified alkoxysilane react in situ to form organic solid skeletal supports in the silicon network. The resulting gel is dried under subcritical conditions and the solid skeletal supports removed by thermal oxidation.
