摘　　要：介绍了TiO2薄膜的超亲水机理,论述了实现TiO2薄膜可见光响应超亲水性的改性技术,主要包括构建粗糙结构薄膜、贵金属沉积、离子掺杂、表面光敏化、半导体复合、TiO2/SiO2复合、多种改性方法联合使用等方法。总结了目前超亲水TiO2薄膜主要存在制备工艺复杂、改性条件苛刻、亲水寿命短等问题,并指出采用溶胶-凝胶法,利用多种改性方法的联合使用是解决这些问题的重要研究方向。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.
