Perfluorodecyltrimethoxysilane (PFDMS) and tetraethyl orthosilicate (TEOS) were hydrolyzed in acid solutions and subsequent copolymerization with ammonia to perform in-situ fluorination of silica (SiO2) nanoparticles. A superamphiphobic coating with a good wear resistance was prepared via stacking the fluorinated SiO2 nanoparticles with a double-sided adhesive tape on a glass substrate. It is indicated that the effective introduction of C-F on SiO2 surface through in-situ fluorination could lower the surface energy. The contact angles of water, edible oil and hexadecane are 165°, 155° and 151°, respectively. After 50-cycle friction test with a sandpaper, the water contact angle still exceeds 155°. However, the oil contact angle drops to 132°. It is a simple and environmentally friendly preparation method.
