摘要
纳米TiO2超亲水薄膜是新型的功能性薄膜,在自洁、防雾和生物兼容性应用等方面起着重要的作用。由于普通的TiO2薄膜禁带宽度较大,亲水性能不佳,使其实际应用受到极大的限制,改性是提高TiO2薄膜超亲水性能的重要手段。因此,对TiO2进行改性就成为该领域的关键课题之一。文中综述了纳米TiO2薄膜的超亲水性机理,以及实现超亲水性表面的改性方法。
Superhydrophilic nano-TiO2 film is a novel material which plays an important volt in self-cleaning, antifogging and biocompatible applications, while hydrophilicity is not satisfactory for normal TiO2 films, so the modification of TiO2 is necessary to improve the superhydrophilic property of the TiO2 films. The recent research progress on mechanisms of superhydrophilicity of TiO2 films, and modification methods are reviewed in this paper.
