Materials and processing of polymer-based electrochromic devices

The demand for polymer based electrochromic device is increasing in recent years due to not only the advantages of conjugated electrochromic polymers such as high color versatility, large optical contrasts, but also their potential applications in flexible devices. In this review, we focus on the state-of-the-art research activities related to the materials and assembly techniques developed for polymer based electrochromic devices. More specifically, we will give an overview of the whole fabrication process including transparent conductive substrate, processing of electrochromic polymer, electrolyte formulation, as well as edge sealant materials and possible encapsulation methods.
