Despite graphene's apparent potential for anti-corrosion coatings, it is cathodic to most metals and can promote corrosion at exposed graphene–metal interfaces. This may accelerate dangerous localized corrosion that can seriously weaken the coated metals.

石墨烯防腐涂料的注意事项

尽管石墨烯具有抗腐蚀涂层的明显潜力，但它对大多数金属都是阴极，可促进裸露的石墨烯-金属界面处的腐蚀。这可能会加速危险的局部腐蚀，从而严重削弱涂层金属。
