通过丝网印刷工艺, 制备了具有高的比表面积的纳米晶氧化钛薄膜, 通过有机/无机复合, 在氧化钛薄膜表面吸附了单层的电变色子, 制备成纳米晶电极并且装配成三明治结构的电致
变色器件. 通过紫外可见分光光度计表征, 该器件的着色态透过率为4%, 退?色态透过率为85%. 其在智能窗、平板显示器、电子书和电子报纸等领域具有潜在的应用前景.
Nanocrystralline TiO2 semiconducting electrode was prepared by using a screen-printing technique. The electrode has very high specific surface-to-volum area which is crucial for the absorption of
more chromophores on the surface. The electrochromic device was assembled by using a sandwich structure after the electrode absorbed chromophore molecules. The electrochromic device was
characterized by UV-Vis spectra. The electrochromic device has a very high transparency at its bleached states (85%), and deep violet at its colored states (4%), which has potential use in smart window, flat
panel display, electric book and electric papers.
