| 摘 要： | 采用一种绿色、温和的氧化体系（H2O/FeCl2/H2O2）合成了结构规整的聚吡咯纳米微球，其结构和形貌采用FTIR和SEM进行表征。以聚吡咯为功能成分，环氧树脂为成膜物质，制备了聚吡咯/环氧树脂复合涂层，研究了其复合涂层在3.0% NaCl溶液中的防腐性能（EIS曲线、开路电位、Tafel极化曲线），结果表明0.6% Ppy-H复合涂层在3.0% NaCl溶液中浸没60天后，仍表现出高的涂层电阻（5.14×107 Ω?cm2）和腐蚀电位 （Vcorr = ?0.202 mV）。

| Abstract: | Polypyrrole nanoparticle was synthesized by chemical oxidative polymerization of pyrrole using H2O/FeCl2/H2O2 as a green，mild oxidizing system. The structure and morphology of the polypyrrole was characterized by IR spectra and SEM. The polypyrrole-epoxy composite coating was then prepared with epoxy resin as the matrix. The corrosion protection property of polypyrrole-epoxy composite coating on Q235 steel was investigated by electrochemical impedance spectroscopy (EIS) technique，OCP and tafel polarization curve in 3.0% NaCl aqueous solution. The results indicated that the 0.6% Ppy-H-containing coatings could offer high protection with the impedance values and corrosion potential remained at 5.14×107 Ω?cm2 and ?0.202 mV after 60 days immersed in 3.0% NaCl aqueous solution. |
