Hydrophobicsilica gel was prepared by sol-gel process using tetraethoxy silicone(TEOS) as raw material, then the surface was chemically modified by diethoxydimethylsilane(DDS).
Super-hydrophobicsilica-based thin films were prepared by sol-gel processing. Both surface energy and roughness were controlled using colloidal silica particles and fluoroalkylsilane.

The influences of hydrophobic group content on the stability of the silica sols and the surface wettability and vapour stability of the silica membranes were investigated.
