Preparation and Self-cleaning Property of Superhydrophilic Ti-containing Mesoporous SiO2 Thin Films

采用溶胶-凝胶/旋转涂覆法在玻璃基板表面制备含钛介孔SiO2薄膜.利用XRD、UV-Vis以及接触角测量仪对薄膜的孔结构和超亲水性进行表征.结果表明,当Ti/Si物质的量比为0～0.05时,薄膜均具有良好的介孔结构;而随着Ti/Si物质的量比的增加,薄膜的介孔有序度下降.即使在无光照条件下,含钛介孔SiO2薄膜也表现出高效的超亲水性.涂有油酸的薄膜在紫外光照射后恢复其超亲水性,且薄膜对甲基橙具有良好的光催化降解效果,表明制备的含钛介孔SiO2薄膜具有良好的自洁净性能.
