| 摘 要： | 目的研究苯胺均聚物/环氧复合涂层和苯胺共聚物/环氧复合涂层在3.5%(质量分数,后同)NaCl溶液中的耐腐蚀性能。方法采用化学氧化聚合法制备苯胺均聚物和共聚物,用SEM,XRD,UV-vis和IR对产物进行表征,并通过电化学测试分析复合涂层在3.5%NaCl溶液中的防腐性能。结果苯胺均聚物/环氧复合涂层和苯胺共聚物/环氧复合涂层都能对碳钢起到不同程度的防腐蚀效果,相比之下,苯胺共聚物/环氧复合涂层的腐蚀电位最高,腐蚀电流密度最小。结论苯胺共聚物在碳钢表面产生了一层钝化膜,使得苯胺共聚物/环氧复合涂层具有较好的耐腐蚀性能。

| Abstract: | Objective To study the anti-corrosion performance of aniline homopolymer / epoxy composite coating and aniline copolymer / epoxy composite coating in 3. 5% NaCl solution. Methods Chemical oxidation polymerization method was adopted to prepare aniline homopolymer and copolymer. The polymers were characterized by SEM, XRD, UV-vis and IR; the anti-corrosion performance of composite coating in 3. 5% NaCl solution was analyzed by electrochemical test. Results Aniline homopolymer / epoxy composite coating and aniline copolymer / epoxy composite coating both had different levels of anti-corrosion effect. In contrast, the aniline copolymer / epoxy composite coating had the highest corrosion potential and the lowest corrosion current density. Conclusion Aniline copolymer produced a layer of passivation film on the surface of carbon steel, granting the aniline copolymer / epoxy composite coating with good anti-corrosion performance. |
