Preparation of TiO_2 Thin Films by Liquid Phase Deposition Methods and their Properties

nansparent TiO2 thin films were prepared by a liquid phase deposition method. The morphology, structure and the change of hydrophilicities under UV illumination of as-prepared films were studied. The result shows that thus prepared films axe dense and uniform, and exhibit a similar hydrophilicity whether the films are annealed or not. Their hydrophilicities are all increased by UV illumination. The films annealed can be entirely wetted by water after UV illumination for a certain time.
