英文摘要	TiO2 films and ZnO doped TiO2-ZnO composite films were synthesized by the sol-gel process. The crystal phase, size of particles and surface morphology of the film samples were characterized by X-ray diffraction and atomic force microscopy. The effects of the annealing temperature, annealing time and thickness of films on the photo-induced amphilicity of the TiO2 and TiO2-ZnO films were investigated using H2O as polarity solution and C6H6 as non-polarity solution. The results show that the annealing temperature and annealing time notably affect the size of particles, the composition and roughness of films, and then lead to a remarkable change in the photo-induced amphilicity of the films. The films annealed at 550C for 2 h with 3 layers has a rutile phase structure by anatase to rutile transformation. The sizes of the crystal grains of the TiO2-ZnO composite film are about 25.2 nm and the film's surface roughness is about 1.815 nm. The contact angle is 5 (4) between the thin composite film and H2O (C6H6), and its photo-induced amphilicity is better than that of pure TiO2 films.
