Abstract
Hexamethyl-disilazane (HMDS) is introduced to replace the hydroxyl groups of ZrO2–SiO2 aerogels (ZSAs) to form inert methyl siloxy surface groups and produce SiO2 particles as the “pinning” particles in air at elevated temperatures. Thus, HMDS/ZSAs exhibit an excellent thermal stability and super-hydrophobic properties with a contact angle of 154°.Keywords
