摘要

采用超声波雾化技术制备TiO2纳米膜, 并对其进行了紫外、扫描电镜、X射线衍射及亲水性能的表征, 讨论了超声波雾化频率对TiO2纳米膜的影响. 分析表明, 此技术可制备均匀致密、粒径为20～80nm、锐钛矿晶相的TiO2纳米膜, 此膜经加热或紫外线照射后具有超亲水性能.

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
