Abstract

The present describes an oxygen functionalized nanoflake (O-GNF), a stable nanofluid in which the graphene nanoflakes remain dispersed or in suspension free of surfactants, and the method of making the oxygen-functionalized nanoflake. The oxygen-functionalized graphene nanoflake (O-GNF and/or O—N-GNF) comprises a single-crystal graphene nanoflake of 5-20 atomic planes comprising a surface oxygen-functionalization, wherein the O-GNF comprise a degree of oxygen functionalization from about 6 to about 25 at. % oxygen by weight of the GNF with a preferred oxygen functionalization of about 14 at. % oxygen.
