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.

提出了双组分二氧化钛/钒氧化物薄膜和粉末的合成和表征，以及它们在电致变色器件（智能窗）和抗菌涂层中的潜在应用。对于膜的制造，将使用在低于100°C的温度下在水溶液中的热水解反应（化学浴沉积）。一般来说，这种方法允许涂覆复杂形状的表面，并提供了一种简单的图案化涂层的路线，以及从气相中传统沉积的经济替代方案。将通过测量有机化合物的光降解来测试膜的光催化活性。通过紫外/维斯光谱和动态光散射实验对薄膜的形貌、微结构和化学成分进行了研究，并对薄膜的形成机理进行了研究。进一步的研究将包括先进的原子力显微镜在流体细胞，以获得力-距离曲线测量模型系统相关的薄膜形成和评估这些结果。
