TiO2 thin films were prepared on modified PET(poly(ethylene terephthalate)) substrates by an improved l-gel method. The as-prepared samples were characterized with X-ray diffraction (XRD), atomic force microscopy(AFM), and UV-Vis spectra. The results show that the interfacial compatibility between organic substrate and inorganic film has been improved after PET substrate was modified with silane coupling agent, and TiO2 films with transparency,uniformity, od adhesion, and high photocatalytic activity can be formed on PET surface. Moreover, the TiO2 thin films with different ratios of anatase/brookite were prepared successfully by controlling the preparation conditions, and the hydrophilicity of the TiO2 thin filmwas improved with proper content of brookite.
