Kurzfassung englisch:
Organically modified silica aerogels have been prepared by sol-gel processing of methanolic solutions of R'Si(OR)3 / Si(OR)4 mixtures (R = 3-methacryloxypropyl or 2-aminoethyl-3-aminopropyl groups), followed by super-critical drying with carbon dioxide. The resulting material is characterized by a very low density (0.14-0.27 g.cm-1), high porosity and surface areas from 250 to 600 m2.g-1 depending on the kind of organic moiety used. The organic groups are easily accessible for further reactions.
