Symmetrical Electrochromic and Electroemissive Devices from Semi-Interpenetrating Polymer Networks
This paper describes the elaboration and optical characterizations of electrochromic devices (ECDs) based on a semi-Interpenetrating Polymer Network architecture. These ECD exhibit contrast ration of 36% in the full visible range and are able to switch 10,000 times at low voltage between +1.2V and -1.2V with only 0.2% of electroactivity lost. By the way, these IPN-based materials present interesting properties in the NIR region.
