Electrochromic Material Based on a Conducting Ladder Polymer
Background Electrochromism is the phenomenon displayed when some type of matter reversibly changes color when a burst of charge is applied. Recent applications of electrochromic materials include electrochromic windows which darken when voltage is added and are transparent when voltage is taken away. Like suspended particle devices, electrochromic windows can be adjusted to allow varying levels of visibility. Electrochromism has also been applied to mirrors that respond to various lighting conditions by changing the color of the actual mirror.
Invention Description Researchers at The University of Texas at Austin have invented a highly stable polymer that appears deep blue in the neutral state, but becomes pale grey upon oxidation and light green or orange upon reduction, depending on the voltage applied.
Highly stable new polymer Very stable to repeated reductive scans but shows slow decomposition on repeated oxidations
Market Potential/Applications Displays, windows, and mirrors
Development Stage Proof of concept
