| titleOfInvention | Electrochromic organic polymer synthesis and devices utilizing electrochromic organic polymers |
| abstract | Large contrast ratio and rapid switching laminated electrochromic (EC) polymer device (50b) includes transparent electrode (42), cathodic EC polymer (44b), gel electrolyte (46), and counter electrode (52). Preferably the cathodic EC polymer is a poly(3,4 propylenedioxythiophene) derivative, PProDOT Me2. Counter-electrode (52) is a conductive coating deposited on transparent substrate, with preferred coatings including gold and highly conductive carbon. Lithography and sputtering can be employed to pattern a gold layer, while screen printing can be employed to similarly pattern graphite. Empirical studies of preferred device indicate a color change of high contrast ratio of transmittance (> 50 %T) is rapidly (0.5 1s) obtained upon applied 2.5V, repeatable to at least 10,000 times, as estimated by electrochemistry. Dual layer EC devices including PProDOT Me2 are also disclosed, as are methods for synthesizing preferred EC polymers. |
