Abstract

VERY RECENT UNRELATED WORK AT GUMBS HAS LED TO SIGNIFICANT DEVELOPMENTS IN CONDUCTING POLYMER TECHNOLOGY. A NUMBER OF NOVEL SOLUBLE CONDUCTING POLYMERS WERE SYNTHESIZED. THE COLOR AND IR TRANSMITTANCE OF THE POLYMERS ARE CONTROLLABLE VIA CONTROL OF THE APPLIED POTENTIAL (OR DOPING LEVEL). FURTHERMORE, THESE POLYMERS HAVE PROVEN PROCESSIBILITY AS THIN FILMS AND ENVIRONMENTAL STABILITY. THE CONDUCTING POLYMERS WITH THE MOST SUPERIOR SPECTRAL PROPERTIES AS IDENTIFIED IN PHASE I WILL BE USED TO FABRICATE ELECTRICALLY CONTROLLABLE VISUAL AND IR SIGNATURES IN THIN FILMS. THE CONDUCTING POLYMERS DEPOSITED FROM SOLUTION ONTO CONDUCTIVE PLASTIC SUBSTRATES AND SOLID ELECTROLYTES WILL ENABLE APPLICATION TO ODD-SHAPED OBJECTS. THIS PANEL PERFORMANCE WILL BE INVESTIGATED TO ILLUSTRATE THE CORRELATION BETWEEN OPTICAL CONTRAST AND APPLIED POTENTIAL. THE WORK WILL ALSO PURSUE THE GOAL TO IMPROVE THE SYNTHETIC TECHNIQUE OF CONDUCTING POLYMERS FOR IMPROVING CONDUCTIVITY AND YIELD. ANTICIPATED BENEFITS/POTENTIAL COMMERCIAL APPLICATIONS - IF THE PROJECT IS SUCCESSFUL, IN ADDITION TO THE ENVISIONED APPLICATION AS LOW TRANSMISSIVITY/REFLECTANCE MATERIALS, APPLICATIONS INCLUDE WHEREVER CONDUCTIVE COATINGS ARE REQUIRED, INCLUDING FOR SUCH USES AS RADAR SIGNATURE REDUCTION, ODD-SHAPED ELECTRODES FOR BATTERIES, ELECTROCHROMIC DISPLAYS, AND ULTRA-FAST ELECTRO-OPTIC SWITCHES.
