摘要: This work investigates the resistance against marine corrosion of an epoxy-based coating modified by addition electrochemically produced and oxidized poly(3,4-ethylenedioxythiophene) (PEDOT). For this purpose, electrodeposition PEDOT was performed on steel electrodes electrochemical polymerization 3,4-ethylenedioxythiophene. The doping level resulting material increased chronoamperometry chronopotentiometry (CP), three different oxidation degrees being achieved. electrical properties such samples, which were used as anticorrosive additives, examined. Furthermore, physical before after conducting polymers characterized using FTIR, thermal analyses, mechanical evaluations. Accelerated tests indicated that polymer with highest amount positive charge per monomeric unit, achieved CP, enhances considerably protection imparted coating. © 2006 Wiley Periodicals, Inc.
