| titleOfInvention | Electrochromic device |
| abstract | An electrochromic device (10) incorporating an electrochromic material (13) and a perfluorosulfonic acid polymer ion conducting layer (14) interposed between a working electrode (12) and a counter electrode (15), characterized by the feature that the perfluorosulfonic acid polymer layer (14) comprises a substantially fluorinated backbone which has recurring pendant groups attached thereto represented by the formula -O-(CFR'f)b-(CFRf)a-SO3-, where a=0-3, b=0-3, a+b= at least 1, and Rf and R'f are independently selected from a halogen and a substantially fluorinated alkyl group having one or more carbon atoms. One example of such a polymer is the copolymer of tetrafluoroethylene and 1,1,2,2-tetrafluoro-2-((trifluoroethenyl)oxy)ethane sulfonic acid having an equivalent weight of about 800. The primary benefit of the present invention is that the electrochromic device darkens sufficiently to be useful when the device is operated at high temperature such as can be encountered in an automobile electrochromic sun roof on a sunny day in a hot climate. |
