摘要：

Using　triblock　copolymer　Pluronic　F127(EO106PO70EO106)　as　the　templating　agent　and　Ti(OBun)4　as　the　inorganic　precursor,　mesostructured　TiO2　thin　films　were　prepared　through　sol-gel　combined　with　evaporation-induced　self-assembly　(EISA).　The　obtained　mesoporous　TiO2　films　have　uniform　mesopores　and　are　free　of　cracks　on　the　surfaces.　The　measurement　results　indicated　that　changing　the　weight　ratio　of　templating　agent　to　inorganic　precursor　could　adjust　the　pore　size　of　the　mesoporous　TiO2　thin　films.　When　the　weight　ratio　of　F127/Ti(OBun)4　varied　from　0.1　to　0.5,　the　pore　size　of　mesoporous　TiO2　films　calcined　at　500°C　changed　from　5.4　nm　to　9.1　nm.　The　obtained　mesoporous　TiO2　thin　films　exhibit　good　hydrophilicity.
