Exploring the Limitations in Molecular and Polymer Electrochromes
Abstract
The Reynolds Group at Georgia Tech proposes the study and development of conjugated redox active molecules and polymers that provide distinct and controllable light absorption properties in the UV-visible-NIR, while also exploring unique switching properties in the mid-infrared region of the electromagnetic spectrum. We seek to understand the fundamental redox and optical properties of vibrantly colored anodically coloring electrochromes (ACE) that switch from a fully clear state with high optical contrast, along with studying low band gap conjugated polymers with long wavelength light absorption allowing switching in the infrared. Capitalizing on our newly developed ACE electrochromic color palette, we propose to focus more deeply on their electrochemical, electrochromic, and switching stability properties. Conjugated polymers having high electrical conductivities with strong IR absorption characteristics, along with especially low band gaps will be studied for their ability to be electrochemically switched in the mid-infrared potentially allowing emissivity modulation on surfaces. These materials are important for multiple AF and DoD applications including the Dimmable Visors program, switchable goggles and windows, dynamic camouflage, and flexible reflective display devices, which can include information-communicating signs, semi-transparent heads-up displays, and devices of interest to the bioelectronics community.
