Titanium dioxide (TiO2) films with different crystalline structures were prepared via solgel dip coating method. The influences of humidity, substrate and catalyst acid on the film quality such as integrality and crystallization were investigated. Pure anatasetyped and rutiletyped TiO2 films with homogeneous and compact nanostructure were prepared under the optimized conditions. The surface characters of both types of TiO2 films were studied by surface energy test and infrared spectrum analysis. The results showed that bothtyped films are able to capture OH radicle, but anatasetyped TiO2 film shows a stronger capability, which leads to a higher surface energy and better hydrophilicity.
