摘　　要：使用具有锐钛矿晶粒的TiO2溶胶,在铜质基材、氧化铝陶瓷片、玻璃载玻片、聚碳酸酯(PC)板、聚氯乙烯(PVC)片、聚对苯二甲酸乙二醇酯(PET)膜、涂料涂层、纸片等多种基材表面涂膜。利用扫描电子显微镜观察了各种基材表面的TiO2薄膜形貌,并对以载玻片为基材的TiO2薄膜的光学性能和光催化性能进行了测试。结果表明TiO2溶胶在多种基材上都能较好地成膜;TiO2薄膜透明,不会遮盖基体材料;TiO2薄膜具有较好的光催化活性。TiO2 sol containing anatase colloidal particles was used to spread on various substrates, such as copper, AI2O3 ceramic, microscope slide, PC plate, PVC sheet, PET thick film, paint coating, and paper sheet, etc. Scanning electron microscope was adopted to investigate the surface morphology of TiO2 films, and the optics property and photocataiytic activity of TiO2 film coated on the microscope slide were also tested. The results show that TiO2 sol has well film forming ability on various substrates. As-prepared TiO2 film is transparent, and will not cover the color of the substrate. Moreover, this film has good photocatalytic activity.
