Abstract

The present invention pro ides a method of providing an electrical contact on a graphene surface, the method comprising: (i) providing a graphene layer structure comprising one or more graphene layers and having a polymer coating on a surface thereof; (ii) contacting one or more portions of the polymer coating with a conductive metal-containing composition comprising a solvent, wherein the polymer coating is soluble in the solvent: and (iii) volatilising the solvent to deposit the conductive metal on the surface of the graphene layer structure.
