摘要

PURPOSE: An electropolymerization method of a conductive polymer nanotube using a porous template, a preparation method of an electrochromic device using the electrochromism of a conductive polymer and an electrochromic device prepared by the preparation method are provided, to improve the electrochromism by increasing the surface area of a conductive polymer. CONSTITUTION: The electropolymerization method comprises the step of injecting the electrolyte solution where an electrochromic conductive polymer precursor is dissolved into the electrochemical reaction cell comprising a first transparent electrode and a porous template formed on the transparent electrode as a working electrode. Preferably the conductive polymer is selected from the group consisting of polypyrrole, polyaniline, polyazulene, polythiophene, polypyridine, polyindole, polycarbazole, polyazine and polyquinone; and the porous template is an anodized metal oxide membrane or a polymer membrane. Preferably the anodized metal oxide membrane is an anodized aluminium oxide membrane or an anodized titania membrane; and the polymer membrane is a porous membrane of polymer comprising polypropylene, nylon, polyester or block copolymer.
