Electrochromism of mixed polyacid films and its application for a smart window

（1）新的电致变色膜Peroxo-polybdotungstates的开发和评估是由金属Mo和W混合物的直接反应形成的（例如， 5 ： 5混合物）与氢过氧化物溶液。一部同源和反常的薄膜（0.4毫米，典型地）是用一个ITO玻璃基底制成的，用旋转涂层作为解决方案。在120 * 进行热处理后，它展示了有机锂离子体中两种逆转性和反应时间的优良电化学。该电影颜色为-1V （vs. Ag/AgCl），表现出较低的平坦吸收光谱。Its color is dark grayish blue and the DELTAOD between-1 V and +0.5 V reaches 0.7 at 670 nm（lambda_<max>）。这种电致色电影的动力学方面也将被讨论。（2）.与聚合物电致色薄膜接触的电泳色薄膜的畸变WO_3和nH_2O是由自旋涂层过氧化物-聚钨状态溶液制造的。与固体聚合物电极接触的薄膜动力学的染色和漂白动力学是通过使用细胞、Li/聚合物/WO_3·nH_2O、ITO的时间测量方法进行的。过渡电流是根据一个新提出的理论的基础来分析的，可以通过一个电压步骤来描述由一个没有参考电极的电池产生的差异控制电流。发现了这两种动力学都是由扩散过程和锂离子化学扩散作用控制的，常见的，约为5x 10^&lt;-12&gt; cm^2/s。（3）.一种电致色窗口原型的制造和评估，一种基于钽氧化物的新型薄膜质子导体是由过氧化物-钽酸开发的。Tungsten氧化物/Prussian蓝色系统中的电致色窗口原型被制造使用该导体作为一个离子导体层。成功和稳定的颜色--漂白性能是被证明的。

(1).Development and Evaluation of New Electrochromic filmsPeroxo-polymolybdotungstates are formed by the direct reaction of a mixture of metallic Mo and W (for example, 5 : 5 mixture) with hydrogen peroxide solution. A homogeneous and amorphous thin film (0.4 mum, typically) is fabricated on an ITO glass substrate by spin-coating using such a solution. After heat-treatment at 120 *, it exhibits electrochromism excellent in both reversibilty and response time in an organic Li-electrolyte.The film colored at -1V (vs. Ag/AgCl) shows rather flat absorption spectrum. Its color is dark grayish blue and the DELTAOD between -1V and +0.5V reaches 0.7 at 670nm (lambda_<max>). Kinetic aspect of such electrochroic films will also be discussed.(2).Coloration of electrochromic film in contact with polymer electrolyteElectrochromic thin film of amorphous WO_3・nH_2O was fabricated by spin-coating a peroxo-polytungstate solytion. Coloration and bleaching kinetics of the film incontact with a solid polymer electrolyte were investigated by a chrono-amperometric method using a cell, Li/polymer/WO_3・nH_2O, ITO.The transition currents were analyzed on the basis of a newly proposed theory to be able to describe the diffusion-controlled current generated by a voltage step in such a cell without a reference electrode. It was found that both kinetics were controlled by the diffusion process and the chemical diffusion coefficients of Li were, in common, about 5 x 10^<-12> cm^2/s.(3).Fabrication and evaluation of an electrochromic window prototypeA new thin film proton conductor based on tantalum oxide was developed from peroxo-tantalic acid. A prototype of electrochromic window in the tungsten oxide/Prussian blue system was fabricated using this conductor as an ion conducting layr. Successful and stable coloration-bleaching performance was demonstrated.
