Electrodeposition of PMeT in a strong Lewis acid (BFEE) can yield good quality, homogeneous, and electroactive PMeT films. On the basis of the study on PMeT, we can take it as a good material to be used in electrochromic devices. Also, PEDOT is a very good electrochromic material for its high optical attenuation (△T), long term stability, and high coloration efficiency. Combining the two thiophene derivatives above we have seen the application potential of this device. Currently, the device PMeT/PEDOT has a stable electrochromic performance and its maximum optical attenuation (△T at 655nm) is around 44%.application/pdf128405 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所電致色變元件聚二氧乙基塞吩聚三甲基塞吩Electrochromic devicePEDOTPoly-methylthiophenereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9392/1/922214E002037.pdf
