Preparation of super-hydropbobic titanium oxide film by sol–gel on substrate of common filter paper

A rough TiO 2 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 ultrav...
