摘要
金属腐蚀给工业生产及安全防护带来了巨大挑战,而涂层防腐作为目前最重要的防腐措施之一,研究如何更为有效地提高涂料防腐性能具有重要意义。GO/PANI复合颗粒作为一种新型材料,具有独特的金属钝化效应及优异的物理屏蔽效应,在有机防腐涂料领域具有很好的应用前景。鉴于目前缺少关于GO/PANI复合颗粒的综述,本文从制备、形貌调控、防腐机理、防腐应用等方面出发,对GO/PANI复合颗粒进行了系统性介绍。首先,对GO/PANI复合颗粒的制备方法(包括溶液聚合、界面聚合以及电化学聚合等合成方法)进行了归纳整理,并对各方法的优缺点进行了总结;然后,分析了单体用量、掺杂酸种类、氧化剂用量等因素对复合颗粒形貌的影响;最后,在简单介绍GO/PANI复合颗粒防腐机理的基础上,系统介绍了其在不同基体涂料中的防腐改性,并对GO/PANI复合颗粒的未来发展方向进行了展望。
Metal corrosion has brought huge challenges to industrial production and safety protection.As one of the most important anti-corrosion measures at present,coating anti-corrosion is of great significance to study how to more effectively improve the anti-corrosion performance of coatings.As a new type of material,GO/PANI composite particles have unique metal passivation effects and excellent physical shielding effects,and have good application prospects in the field of organic anti-corrosion coatings.In view of the current lack of review on GO/PANI composite particles,this article systematically introduces GO/PANI composite particles from the aspects of preparation,morphology control,anti-corrosion mechanism,anti-corrosion application,etc.First,the preparation methods of GO/PANI composite particles,including solution polymerization,interfacial polymerization and electrochemical polymerization,are summarized,and the advantages and disadvantages of each method are summarized.Then the effects of factors such as the amount of monomer,type of doping acid,and amount of oxidant on the morphology of the compo-site particles are analyzed.Finally,on the basis of a brief introduction to the anti-corrosion mechanism of GO/PANI composite particles,the anti-corrosion modification in different matrix coatings is systematically introduced,and the future development direction of GO/PANI composite particles is prospected.
