Preparation and Characterization of Super-Hydrophilic TiO2/SiO2 Composite Thin Films

Abstract

Abstract: The uniform transparent TiO₂/SiO₂ composite thin films were prepared via sol-gel processing on the soda lime glass substrates. The addition of SiO₂ to TiO₂ thin films can suppress the grain growth of TiO₂ crystal in the TiO₂ thin films, increase the hydroxyl content Of TiO₂ film, low the contact angle for water of TiO₂ films and enhance the hydrophilic property of TiO₂ films. The super-hydrophilic TiO₂/SiO₂composite films with the contact angle of 0° were obtained by the addition of 10mol%~20mol% SiO₂.

Key words: TiO₂/SiO₂ composite thin films, super-hydrophilic property, preparation, characterization
