Study on TiO2 Light-Induced Amphiphilicity on the Erased Plate

Using Sol - gel prepared SiO₂ and TiO₂ thin film and coating on the glass substrate, this paper studied TiO₂ thin films as a new type of printed material with the illumination time and the infiltration of the relationship between light intensity and illumination time on the water-based ink on film surface adsorption. The results show that: TiO₂ thin film by ultraviolet irradiation, its hydrophobic property drastically reduced, and showed super hydrophilic properties and water contact angle down to 5°or less. Thesis results show that: TiO₂ thin film with light-induced amphiphilicity expected as a new type of environmentally friendly reusable printing plate.
