【中文摘要】 利用改进的溶胶-凝胶法在经表面改性的PET(聚对苯二甲酸乙二醇酯)表面制备得到TiO2薄膜.利用X射线衍射(XRD)、原子力显微镜(AFM)、UV-Vis透光率曲线、接触角测试仪等测试手段对TiO2样品的性能进行表征.结果表明,PET表面过渡层的引入有效地改善了有机基底与无机薄膜之间的界面相容性,在其表面形成透明、均一、附着力良好且具有光催化活性的TiO2薄膜.通过控制实验过程,在低温下成功制备了不同锐钛矿/板钛矿比的TiO2薄膜,同时发现适量板钛矿相的存在能有效提高薄膜的光致亲水性. 【英文摘要】 TiO2 thin films were prepared on modified PET(poly(ethylene terephthalate)) substrates by an improved sol-gel method. The as-prepared samples were characterized with X-ray diffraction (XRD), atomic force microscopy (AFM), and UV-Vis spectra. The results show that the interfacial compatibility between organic substrate and inorganic film has been improved after PET substrate was modified with silane coupling agent, and TiO2 films with transparency, uniformity, good adhesion, and high photocatalytic activity ...
