Abstract
Electrically active, cathodically coloring electrochromic polymers are blended with a non-electrochromic, non-electrically conductive binder polymer to provide an electrochomic composition with greatly enhanced performance in an electrochromic device over time. It is also found that blending an electrochromic polymer with a non-coloring electroactive material allows for greater design in preparing electrochromic devices as it enables the use of a higher amount of typically low coloring anodic materials due to increased need for charge balancing.
