摘要

Organically modified aerogels, processes for their preparation by surface modification of the aqueous gel, without prior solvent exchange, and subsequent drying, and their use ;The present invention relates to novel, organically modified aerogels, to a process for producing them in which ;a) a hydrogel is introduced as initial charge, ;b) the hydrogel obtained in step a) is subjected to surface modification, and ;c) the surface-modified gel obtained in step b) is dried, and to their use. ;The present invention additionally relates to novel, organically modified wet gels, to a process for producing them and to their use.
