  • Electrochromic polymers and polymer electrochromic devices
    Patent number: 6791738
    Abstract: The subject invention pertains to electrochromic polymers and polymer electrochromic devices. In a specific embodiment, two complementary polymers can be matched and incorporated into dual polymer electrochromic devices. The anodically coloring polymers in accordance with the subject invention can allow control over the color, brightness, and environmental stability of an electrochromic window. In addition, high device contrast ratios, high transmittance changes, and high luminance changes can be achieved, along with half-second switching times for full color change. Also provided are electrochromic devices such as advertising signage, video monitors, stadium scoreboards, computers, announcement boards, warning systems for cell phones, warning/information systems for automobiles, greeting cards, electrochromic windows, billboards, electronic books, and electrical wiring. The subject invention also provides for the use of complementary electrochromic polymers in the manufacture of electrochromic devices.
