Abstract
Glass as a traditional building material have been widely used in all aspects of daily life, such as car windshields, glass curtain wall, home improvement materials, which performance played an important factor in the life. Self-cleaning glass appeared and produced has opened a novel door to the green development of material. In this paper, the self cleaning film including NbOX ，TiO2，[NbOX 、TiO2] composite film，[NbOx/TiO2]，TiNbO5，[TiNbO5 、NbOX] composite film and [NbOx/ TiNbO5，TiTaO5] was prepared via LBL spin-coating method starting from TiO2、 NbOx 、TiNbO5and TiTaO5 nanosheets , which have been fabricated from the layered compound. Typically, scanning electron microscopy (SEM) was employed to detect the morphology of film. At the same time, the decomposition of MB under the UV light was utilized to probe the photocatalytic property. Finally, the contact angle was charactered to illustrate the hydrophilic property. The results indicated that: the [NbOX,TiO2] composite film heated under 450 ℃ possessed super-hydrophilic properties, high transmittance under the visible region and better photocatalytic performance, and abrasion to the scratch, which was sufficient for most vehicles with self-cleaning glass.
