We fabricated an intrinsically stretchable electrochromic film of a composite of PEDOT:PTS, which is a conductive polymer that shows electrochromism, and polyurethane by spin coating followed by chemical polymerization. The fabricated film showed reversible electrochromism upon the application of constant voltage, which showed that it works as a stretchable electrochromic film without an underlying conductive substrate. The electrochromism of the film was investigated in detail by methods such as color analysis of the video.
