摘要/描述

Nanoscale SiO2-TiO2 composite thin films with the thickness of about 100nm were prepared by solgel method at room temperature in air. The chemical states of the elements on the surface and near the surface were measured by XPS. The results showed that the Ti on/near the surface of the thin films existed not only as TiO2 but also as Ti2O3. Part of the TiO2 was changed to Ti2O3 after UV irradiation. The crystalline structure of the TiO2 in the SiO2-TiO2 thin films was anatase with the crystallite size of 14-20nm. It was found that the thin film prepared at room temperature in air has good superhydrophilic property and has strong adherence to the substrate.

关键词: superhydrophilic, ， room temperature, ， crystallite size, ， binding energy, ， XPS, ， adherence
