摘要
导电聚苯胺(PANI)因其良好的化学稳定性、导电性、吸附性等在金属防腐领域作为缓蚀剂具有重要应用潜力。然而,聚苯胺在水溶液中极差的溶解性严重限制了其作为缓蚀剂的应用,有效提升其溶解性和增强在金属表面的吸附性是导电聚苯胺类缓蚀剂的研究重点。介绍了导电聚苯胺的结构性质和缓蚀机理,综述了导电聚苯胺类缓蚀剂的小分子酸掺杂改性、线性大分子酸掺杂改性、苯胺衍生物共聚合改性、复合改性、低分子量改性和协同效应改性的方法,简要分析了不同改性方法的优缺点,以期为后续导电PANI改性研究提供参考。
Conductive polyaniline has great application potential as a corrosion inhibitor in metal anti-corrosion field due to good chemical stability, electrical conductivity and adsorption.However, the poor solubility of polyaniline has severely limited its application as a corrosion inhibitor, so the effective improvement of solubility and enhancing the adsorption performance on the metal surface are the research focuses as a polyaniline corrosion inhibitor.The structural properties and corrosion inhibition mechanisms of conductive polyaniline were introduced, particularly, the modification methods such as small molecule acid-doped modification, linear macromolecular acid-doped modification, aniline derivative copolymerization modification, composite modification, low molecular weight modification and synergistic effect modification were reviewed, the advantages and disadvantages of different modification methods were briefly analyzed, in order to provide a reference for the subsequent modifications of conductive polyaniline.
