摘　　要：聚苯胺因其可逆的氧化还原特性在金属腐蚀与防护领域具有广阔的应用前景,目前有关改性聚苯胺对涂层附着力、阻隔性能以及钝化机理的研究比较零散,缺乏系统总结。通过对单一聚苯胺分散性差、疏水性弱等缺陷的分析,报道近年来改性聚苯胺在防腐涂料领域中的研究思路和研究进展,比较不同条件下改性策略的优劣,归纳聚苯胺结构与涂层耐腐蚀性之间存在的联系。进一步论证柔性、疏水基团取代聚苯胺有利于提升涂层抗渗性,改变掺杂剂以及与纳米氧化物、石墨烯等原位聚合制备复合填料也是提升涂层防腐性能的有效途径。展望该行业未来研究和发展的趋势,可为今后聚苯胺的改性工作提供理论指导。Polyaniline has promising prospects in the field of metal corrosion protection due to its reversible redox properties.Investigation on the adhesion,barrier properties and passivation mechanism of modified polyaniline composite coatings is relatively scattered,which needs to be summarized logically.Through the analysis of defects such as poor dispersion and weak hydrophobicity of ordinary polyaniline,this paper reports the research ideas and advances of anticorrosive coatings incorporated polyaniline and its derivative in recent years.The merits of modification strategies under different condition are compared and the relevance between the structure of polyaniline and the corrosion resistance is concluded,further demonstrating that flexible or hydrophobic substituents are conducive to the impermeability of organic coatings.There is also other polyaniline modification approach from the aspects of altering dopant and in-situ polymerization with nano-oxides or graphene for improving anticorrosion performance.The future development trends of the industry are prospected,providing theoretical guidance for the future study.
