摘要： 采用溶胶凝胶法制备具有不同晶体结构的TiO2薄膜，研究了环境湿度、基体材料和催化剂酸种类等条件对薄膜质量（如完整性和晶体结构的单一性等）的影响，并在优化后的工艺条件下分别制备出了具有单一锐钛矿相和单一金红石相的均匀致密的纳米晶TiO2薄膜，结合表面能测试和红外光谱分析研究了两种不同晶体结构的TiO2的表面性能，结果发现锐钛矿型TiO2和金红石型TiO2表面都能捕获OH基团，锐钛矿型TiO2表面有更多的OH基团，表面能更高，表面亲水性更好.

Abstract: Titanium dioxide (TiO2) films with different crystalline structures were prepared via solgel dip coating method. The influences of humidity, substrate and catalyst acid on the film quality such as integrality and crystallization were investigated. Pure anatasetyped and rutiletyped TiO2 films with homogeneous and compact nanostructure were prepared under the optimized conditions. The surface characters of both types of TiO2 films were studied by surface energy test and infrared spectrum analysis. The results showed that bothtyped films are able to capture OH radicle, but anatasetyped TiO2 film shows a stronger capability, which leads to a higher surface energy and better hydrophilicity.
