A SOLID-STATE ELECTROCHROMIC DEVICE BASED ON 2 OPTICALLY COMPLEMENTARY CONDUCTING POLYMERS

Materials for high-performance electrochromic windows must fulfill var ious requirements, e.g., high optical contrast, fast response time, an d stability. The construction and characterization of a device with te chnologically interesting properties are described. The device uses tw o active polymer electrode materials with complementary electrochromic behavior and a complex between a commercial elastomer and LiClO4 as t he solid electrolyte. The cell can be assembled under atmospheric cond itions and exhibits good contrast between the colored and bleached for ms.
