The nano-films of TiO2 were prepared by using ultrasonic atomization technology. The films were characterized by the absorption of UV spectrum. Their surfaces were viewed by the scanning electronic microscope (SEM) and the X-ray diffraction. The hydrophilic effect of the films was determined. The influence of the frequency of ultrasonic atomization on the nano-films of TiO2 was discussed. The analytic results show that the resulting products are a nano-film of TiO2 as uniformed crystal of anatase with the particle diameter of 20～80nm. After heated or irradiated by UV radiation, the two films become super-hydrophilic materials.
