Abstract

Abstract: Based on using sol -gel to prepare SiO₂ and TiO₂films and coating on the glass substrate, this paper studied on TiO₂ thin film under UV irradiation and its super-hydrophilic properties changing with the light of time, analyzed the SiO₂ film on the cover TiO₂ film on its friction properties. The results showed that: hydrophobicity of TiO₂ thin films by ultraviolet irradiation drastically reduced, showed super hydrophilic properties and water contact angle could reach 5? below; when the films was coated on the glass slide, they showed the good rubbing and weather resistance. These results show that: the super hydrophilicity of TiO₂ is expected as a new type of environmentally friendly reusable printing plate.

Key words: SiO₂, TiO₂ thin film, super-hydrophilic, abrasion resistance, printing plate
