Coating of graphene on metal surface can be carried out by various ways like chemical vapour deposition (CVD), electrodeposition, solution processes etc. Excellent adhesion can be obtained by using CVD process but it possesses limitation as this CVD can be carried to limited types of surfaces . By modifying the ionic liquid, graphene oxide may be utilised to alleviate the friction and wear of epoxy . Graphene oxide is made by oxidising graphite with the Hummers technique .
