Electroactive Polymers with Semi-IPN Architectures for Electrochromic Devices

Semi-Interpenetrating Polymer Network architecture containing either PEDOT or PProDOT-Me2 leads to interesting electrochromic devices (ECDs) without need of transparent conducting electrode. Upon applied potential between +1.2 V and −1.2 V these ECDs exhibit 30% contrast variation in the full visible range. Furthermore, the control of the PEDOT content up to 0.3 leads to semi IPN-based materials with interesting change in the reflective properties in the Near Infrared region.
