摘要
采用溶胶-凝胶法制备了聚乙二醇(PEG2000)改性TiO2薄膜,研究了PEG2000添加量对TiO2薄膜的微结构、表面形貌、透射率和自清洁性能的影响。以紫外光为光源,分析了PEG2000含量对TiO2薄膜光催化活性的影响。结果表明,所制备的薄膜均为锐钛矿结构;通过调节PEG2000的添加量,可以调控薄膜的微观结构,从而调控TiO2薄膜的光学性能和自清洁性能。
Abstract
By the sol-gel method, the polyethylene glycol (PEG2000) doped TiO2 films are prepared. The effects of additive amount of PEG2000 on the microstructure, surface morphologies, transmissivity, and self-cleaning properties of TiO2 films are investigated. With the ultraviolet lights as light sources, the effects of PEG2000 concentrations on the photocatalytic activity of TiO2 films are analyzed. The results show that all the structures of the prepared films are anatase; the microstructure of TiO2 films can be regulated and controlled by the regulation of the additive amount of PEG2000 and thus their optical and self-cleaning properties are controlled.
