본 발명은 전기 활성 양극 착색, 전기변색 중합체를 비-전기변색, 비-전기 전도성 결합제 중합체와 블렌딩하여 시간 경과에 따라 전기변색 장치에서의 양극 착색, 전기변색 중합체의 성능을 크게 향상시키는 것에 관한 것이다. 또한, 블렌드의 개선된 물리적 특징, 예를 들면 도막 두께, 내구성 등 이외에, 블렌드를 포함하는 장치의 색상 공간 및 색상 강도를 비롯한 색채화적 성질은 니트 중합체를 사용하는 경우보다 내구성이 더 크며, 특정의 경우에서 블렌드에 의하여 제공되는 색상 공간 및 색상 세기는 니트 중합체로부터 얻을 수 있는 것보다 더 우수하다. Blending an electrically active, anodically coloring, electrochromic polymer with a non-electrochromic, non-electrically conductive binder polymer greatly enhances the performance of the anodically coloring, electrochromic polymer in an electrochromic device over time. In addition to improved physical characteristics of the blend, e.g., film build, durability etc, the coloristic properties, including color space and color strength, of the device comprising the blend are more durable than when using the neat polymer, and in certain instances, the color space and color intensity provided by the blend is superior to that available from the neat polymer.
