Abstract

rough TiO film was fabricated by sol-gel technique, the film exhibits perfect super-hydrophobicity with a contact angle of 150° and glide angle of about 5° after being modified with octyltrimethoxysilane. The super-hydrophobicity was converted to super-hydrophilicity by the irradiation of ultraviolet light for 20 h, the irradiated super-hydrophilic film evolves to be hydrophobic with a contact angle of about 120° on the condition of being placed in dark for 2 weeks. Finally the property of super-hydrophobicity of TiO film modified with octyltrimethoxysilane was discussed on the basis of Cassie's theory. [ABSTRACT FROM AUTHOR]
