Preparation and Characterization of Nano-films of TiO2 Based on Ultrasonic Atomization Technology

doi:10.3724/SP.J.1077.2006.00719

Abstract

Abstract: 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.

Key words: nano film, ultrasonic, atomization, TiO2
