| 摘 要： | 为了研究聚苯胺(PANI)/银复合薄膜对不锈钢的防腐蚀性能,采用循环伏安法在不锈钢表面沉积一层Ag后,再通过对苯胺的电化学聚合制备了PANI膜。利用阳极极化法和交流阻抗法研究了PANI/Ag复合膜的耐蚀性及其影响因素。结果表明:在0.1 mol/L NaC l溶液中,不锈钢覆盖复合膜后的自腐蚀电位比无膜时有所提高,其耐蚀性能得到增强;电化学聚合溶液浓度、扫描速率及扫描上限等因素对复合膜耐蚀性的影响情况为:电解液中苯胺和硫酸浓度过高或过低都会影响膜的致密度,从而影响复合膜的耐蚀性;电化学参数的变化会影响复合膜的聚合速率,使复合膜的抗腐蚀能力不同;当苯胺单体浓度为0.2 mol/L、硫酸浓度为1 mol/L、扫描电位上限为1 V、扫描次数为50次、扫描速率为50 mV/s时,采用循环伏安法聚合苯胺,可形成沉积致密度高、耐蚀性好的复合膜。

| Abstract: | Silver film was prepared on the surface of stainless steel by using a cyclic voltammetric method.Then polyaniline(PANI) film was prepared atop Ag film via electrochemical polymerization of aniline.The corrosion resistance of resultant PANI/Ag composite films and main factors influencing the corrosion resistance were investigated by using an anodic polarization method and alternating current electrochemical impedance spectroscopy.Results show that PANI/Ag composite films can increase the corrosion potential ... |
