High Contrast IR Switching by Redox Active Conjugated Polymers
Abstract
We propose to utilize IR switchable polymers on a reflective electrochromic device platform as a means of modulating IR radiation and heat on surfaces. We seek to understand structure-property relationships that will lead us to design and synthesize polymers with optimized IR contrast. These CPs will be processed from solution, ultimately allowing flexible, and large area devicesto be constructed. Redox doping will be carried out electrochemically allowing the doping level to be precisely controlled, and the CP:dopant ion interactions to be probed, which may affect IR contrast. Employing front facing electrochromic devices constructed with porous electrodes, mechanically flexible reflective/absorptive devices will be prepared to modulate longwavelengthradiation at the electrode surfaces. We will measure optical contrast in the visible, near-infrared, and mid-infrared, exploring the optimal reflective contrast ratios possible, switching times between states, and optical memory at open circuit. We will employ our backcontact technology to build a 3x3 array of these pixels as a demonstration that multi-pixelated surfaces can ultimately be attained.
