Electrochromic film

Abstract

The present invention relates to an electrochromic film. The invention demonstrates the electrochromic effect of a single substrate film by applying electronic current to induce a reversible oxidation-reduction reaction of an organic electrochromic layer. The electrochromic film can attach to a surface of an object with the using of an adhesive layer.
