Commentary

A cautionary note on graphene anti-corrosion coatings pp834 - 835

Chenlong Cui, Alane Tarianna O. Lim & Jiaxing Huang

doi:10.1038/nnano.2017.187

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.
