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.
