文摘
Multi-aromatic conducting polymer films, poly(N-phenyl-1-naphthylamine) (PPNA), were prepared by usinga combination of vapor deposition and electrochemical polymerization. The PNA monomer film was vapordeposited on an indium-tin oxide (ITO) glass and was then electropolymerized using cyclic voltammetry ina 1 N HClO4 aqueous solution. An electrochemical rubbing effect happened on the monomer film using theabove combined process, producing a robust electrode material of PPNA film in the electrochromic device:ITO/PPNA film//PU-LiClO4//PEDOT:PSS/ITO, where poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) is PEDOT:PSS, and polyurethane is PU. Short response time (ca. 10 s) was attained from coloringto bleaching processes. After 200 switching, the stable Coulombic efficiency and optical contrast possess thevalues of 108 and 28%, respectively.
