摘　　要：用电化学合成的方法在氧化钢锡（ＩＴＯ）导电玻璃上分别镀上了电致变色的三氧化钨（ＷＯ３）和聚苯胺（ＰＡＮＩ）膜，并将这两种ＩＴＯ玻璃用高分子电解质粘结形成灵巧窗口．当外加电压在－１．４Ｖ～＋１．４Ｖ之间变化时，灵巧窗口在可见光区具有很显著的透光率变化．当用二氧化钛（ＴｉＯ２）修饰聚苯胺形成ＰＡＮＩ－ＴｉＯ２复合膜代替上述窗口中的ＰＡＮＩ膜时，可以在更小的外加电压变化范围内（－１．４Ｖ～＋１．０Ｖ）达到同样的变透光率效果．The electrochemical and optical properties of a smart window consisting of two complementary elecrtochromic materials, namely polyaniline and tungsten oxide, have been investigated. The kind of smart window depcts remarkable properties for light modulation in the visible region. By Changing the applied voltage from-1.4V to +1.4V, for example, the transmission is reduced from 0.770 to 0.178 at 550nm, and from 0.680 tO 0.085 at 720nm. A smart window consisthe of Polyanilinetitaniumdioxide composite film and tungsten oxide filn has also ho investigated. It deminstrates sharp light modulation in the visible region, and as a result of the addition ofTiO2, the requesite variation in applied potential for the equivalent amount amount of electro chromic reduced. For exzmple, by changing the applied voltage from-1.4V to + 1.0V,the transmission is changed from 0.745 to 0.048 at 720nm.
