| Abstract: | The mechanisms of TiO2 films superhydrophlicity are introduced.The methods for realizing visible-light-driven superhydrophilicity of TiO2 thin film,including constructing rough films,precious metal deposition,ion doping,surface sensitization,semiconductor coupling,TiO2/SiO2 compositing and multiple modifications are discussed.In addition,the existing problems of superhydrophilic TiO2 are addressed,such as complicated preparation technology,rigid modification conditions and short time of superhydrophilicity.Using the sol-gel method and combining multiple modifications are effective methods to resolve these problems in the future. |
