Abstract: TiO2 thin films synthesized from aqueous TiOSO4 solution were characterized by X-ray diffractometry (XRD), atomic force microscopy (AFM) and UV-Vis transmittance measurements. The photoinduced hydrophilicity of the TiO2 thin films was investigated. Results show that the as-synthesized TiO2 thin films have good hydrophilicity; the hydrophilicity can be improved by increasing annealing temperatures at 100-500℃.

Key words: TiO2, thin films, hydrophilicity, contact angle
