传统的聚苯胺颗粒粗大,在涂料中分散性差,涂料制备成本高.以聚苯胺/凹凸棒石(PANI/ATP)与磷钛粉为防腐蚀填料,环氧树脂为成膜物质,制备了聚苯胺/凹凸棒石与磷钛粉(PAP-C)协同型防腐蚀涂料.通过电化学交流阻抗(EIS)和开路电位(OCP)对其涂层防腐蚀性能进行了表征,探讨了PANI/ATP用量、颜基比和分散剂用量对PAP-C涂层的力学性能和防腐蚀性能的影响.结果表明:PAP-C涂层较磷钛粉(P-C)涂层具有更好的防腐性能及更高的耐冲击强度;当PANI/ATP用量为4％,颜基比为1.00,分散剂用量为1.0％时,PAP-C涂层耐冲击强度50 cm,附着力1级,柔韧性2 mm,可耐中性盐水(3.5％NaCl)腐蚀60 d.
