Aerogels with hybrid organo-inorganic 3D network structure based on polyfluorinated diacids

摘要

A novel type of organo-inorganic polyfluorinated aerogels is developed, based on aminopropylsilane moieties which are linked together by difluoromalonic or octafluoroadipic acid fragments. Supercritical drying was performed in isopropanol, carbon dioxide, methyl-tert-butyl ether and hexafluoroisopropanol. All the aerogels were found to be poorly hydrophobic, but highly transparent.
