Abstract
Electrochromic materials have been around the lab for decades but the fusion of new and old ideas and new materials have brought us more stable and unique devices. We have developed a family of aromatic amine/diimide polymeric materials that show multiple coloration states, are stable to air and water and show in the optimized cases, <10% optical degradation over 200,000 cycles in devices. Both switching speed and stability require a careful choice of electrochromic material, solid-electrolyte separator and counter- electrode materials. Ag nanoparticles can also be used to direct optical coloration changes and we will report our initial findingsand opinions in this area.
