Abstract:

Polythiophene was prepared via the electropolymerization of 2,2＇∶ 5＇,2″-terthiophene （ 3T） ,and the electrochromic behaviors of polythiophene film were investigated,revealing a reversible color change from orange yellow to navy blue for the film with applied voltage in liquid electrolyte. Moreover,a solid-state electrochromic indium tin oxide （ ITO） /polythiophene/conducting gel/ITO device was fabricated,with polythiophene as the active electrochromic layer,and a similar color change was also observed for the device with applied voltage.

Key words: electropolymerization, polythiophene, electrochromic behavior, solid-state electrochromic device
