Growth mechanism of two-component titania/vanadium oxide thin films from aqueous solutions

提出了双组分氧化钛/钒薄膜和粉末的合成和表征及其在电致变色器件（智能窗口）和抗菌涂层中的潜在应用。为了制备薄膜，将使用温度低于100°C的水溶液中的热水解反应（化学浴沉积）。一般来说，这种方法允许对复杂形状的表面进行涂层，并为图案涂层提供了一种简单的途径，同时也为传统的气相沉积提供了经济的选择。将通过测量有机化合物的光降解来测试薄膜的光催化活性。对膜的形貌、微观结构和化学成分的研究将结合紫外/可见光谱和动态光散射实验对膜的形成机理进行研究。进一步的研究将包括在流体细胞中的先进原子力显微镜，以获得与膜形成相关的模型系统的力-距离曲线测量和这些结果的评估。

The synthesis and characterization of two-component titania/vanadium oxide films and powders with respect to their potential application in electrochromic devices (¿Smart Window¿) and antimicrobial coatings is proposed. For the fabrication of the films thermohydrolytic reactions in aqueous solutions at temperatures below 100°C will be used (Chemical Bath Deposition). In general this procedure allows the coating of complex shaped surfaces and provides a simple route for patterned coatings as well as an economical alternative to conventional deposition from the gas phase. The films will be tested for photocatalytic activity by measuring the photodegredation of organic compounds. Investigations on morphology, microstructure and chemical composition of the films will be combined with studies on the formation mechanism by UV/VIS spectroscopy and dynamic light scattering experiments. Further studies will include advanced atomic force microscopy in fluid cells to obtain force-distance curve measurements of model systems related to the film formation and the assessment of these results.
