High Contrast and Dynamic Electrochromic Display with Thin Solid Hyper-Branched Polymer Film
A new hyperbranched electrochromic (EC) polymer containing many viologen units was developed. The EC polymer film was easily fabricated by a spin coating method and employed as thin EC display film. All-solid EC display was constructed with polymeric electrolyte gel and hyperbranched polymer. The EC display was operated with good contrast and rapid response at low bias voltage, 2.5V.
