Abstract: Biomimetic Fe-TiO2 films were prepared by the sol gel method using polyethylene glycol (PEG) as a pore direction agent. The thermal decomposition behavior of the gel film was analyzed by TG-DSC. The effect of the gel heat-treatment regime on the morphology，phase and hydrophilicity of the film was investigated by scanning electron microscope，X-ray diffraction and contact goniometer，respectively. The results showed that a constant temperature regime produced a continuous film with well-distributed 2—5 μm spherical pores，while a temperature programming regime formed a well-distributed about 100μm sunflower-like spots on the film surface. Amorphous and anatase films could be obtained by using no ageing precursor sol and aged sol at 80℃ for 8h，respectively. Doping Fe3+ and forming pores could remarkablely increase the hydrophilicity of the TiO2 film. Furthermore，hydrophilicity of the film produced by the constant temperature regime was superior to that of the film produced by the temperature programming regime.
