新型车辆用自清洁玻璃的制备与抗菌性能研究

摘要玻璃作为传统的建筑材料广泛地应用于工业和日常生活各个方面，例如汽车挡风玻璃、玻璃幕墙、家装材料等，而这些材料的性能直接关系到人民的生活质量。自清洁玻璃的产生，为汽车玻璃产业创造了一片新的景象。本论文中，以制备出的TiO2、 NbOx 、TiNbO5和TiTaO5纳米片为原料，使用层层自组装旋涂法镀膜介绍了涂有不同薄膜（NbOX ，TiO2，[NbOX 、TiO2]复合，[NbOx/TiO2]，TiNbO5，[TiNbO5 、NbOX] 复合，[NbOx/ TiNbO5，TiTaO5]）的自清洁玻璃的光学性能探究。利用扫描电镜(SEM)观察薄膜的表面形貌，以薄膜对亚甲基蓝的光降解表征自清洁玻璃的光催化能力，以接触角分析表明薄膜的超亲水性能。结果表明：在热处理450℃下，[NbOX ，TiO2]复合薄膜具有超亲水性能、高透光性、光催化性能和耐刮擦能力。因此，此种复合薄膜适用于车辆用自清洁玻璃。9110

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.
