| 摘 要： | 目的 制备一种石墨烯基导电防腐涂料，评价和分析涂料的长效防腐机理和导电机制。 方法 以环氧树脂为主要成膜物质，通过导电填料和防腐填料搭配并配方优化，制备新型石墨烯导电防腐涂料。通过基本性能的检测、电化学工作站测试、中性盐雾实验、实地埋样试验及大电流冲击实验，探究导电防腐涂层的防腐机理和失效衍化过程，并考察涂层的电气性能。结果 制备的导电防腐涂料不仅基本性能（附着力、耐冲击性及涂层结合强度）优异，还具有优异的耐水、耐中性盐雾和耐化学品性，经盐雾实验1500 h测试后，涂层完整且湿附着力仍表现良好。电化学系统测试表明，在3.5%NaCl溶液中浸泡60 d后，涂层仍具有较好的防护性能。涂层的体积电阻率和表面接触电阻分别为0.21 Ω×cm和6.32 Ω×cm2。经5 kA大电流冲击试验5次后，未发现涂层开裂、剥落和烧毁等情况，表明若干次大电流冲击对导电防腐涂层无明显影响。 结论 该配方的导电防腐涂料具有较好的耐蚀性及电气性能。
