Abstract Graphene is cathodic to most metals and can cause promoted corrosion to metals. Herein, we demonstrate that tuning oxygen reduction reaction (ORR) activity of graphene through fluorination modification is an effective strategy that can inhibit the corrosion-promotion activity of graphene. It is revealed that the cathodic ORR activity of partially fluorinated graphene (PFG) decreases with the increase of fluorine (F) content, which consequently increases the depolarization resistance of the cathodic ORR during corrosion. Especially, PFG containing 15.2 wt.% F exhibits a completely negligible corrosion-promotion activity. Furthermore, PFG can also improve the barrier property of polyvinyl butyral coating.

通过氟化改性调节石墨烯的氧还原反应活性以抑制其腐蚀促进活性

摘要 石墨烯对大多数金属具有阴极作用，可促进金属腐蚀。在此，我们证明通过氟化改性调节石墨烯的氧还原反应 (ORR) 活性是一种有效的策略，可以抑制石墨烯的腐蚀促进活性。结果表明，部分氟化石墨烯（PFG）的阴极ORR活性随着氟（F）含量的增加而降低，从而增加了阴极ORR在腐蚀过程中的去极化电阻。特别是，含有 15.2 wt.% F 的 PFG 表现出完全可以忽略不计的腐蚀促进活性。此外，PFG还可以提高聚乙烯醇缩丁醛涂料的阻隔性能。
