“…Different oxides have been coupled with graphene including MgO to enhance the interfacial bonding between graphene and magnesium substrates [237], praseodymium-decorated graphene for the protection of a magnesium AZ31 alloy [238], while silver nanoparticles have been combined with GO to give protective coatings with antibacterial activity [62,239,240]. Additional metals/oxides such as TiO 2 [241][242][243], ZnO [244][245][246], CeO 2 [247] and NiCo [248] have been coupled with graphene to enhance dispersion and corrosion protection. Moreover, antimony tin oxide powder has been mixed with graphene sheets and added to epoxy coatings to give protective coatings with conducting properties [249].…”

Corrosion is a naturally occurring phenomenon and there is continuous interest in the development of new and more protective coatings or films that can be employed to prevent or minimise corrosion. In this review the corrosion protection afforded by two-dimensional graphene is described and discussed. Following a short introduction to corrosion, the application of graphene in the formulation of coatings and films is introduced. Initially, reduced graphene oxide (rGO) and metallic like graphene layers are reviewed, highlighting the issues with galvanic corrosion. Then the more successful graphene oxide (GO), functionalised GO and polymer grafted GO-modified coatings are introduced, where the functionalisation and grafting are tailored to optimise dispersion of graphene fillers. This is followed by rGO coupled with zinc rich coatings or conducting polymers, GO combined with sol-gels, layered double hydroxides or metal organic frameworks as protective coatings, where again the dispersion of the graphene sheets becomes important in the design of protective coatings. The role of graphene in the photocathodic protection of metals and alloys is briefly introduced, while graphene-like emerging materials, such as hexagonal boron nitride, h-BN, and graphitic carbon nitride, g-C3N4, are then highlighted.
