▎ 摘  要

NOVELTY - Producing (P1) chemically functionalized nano graphene material involves mixing starting nano graphene material having edges and two primary graphene surfaces, an azide or bi-radical compound, and an organic solvent in a reactor, and allowing a chemical reaction between the nano graphene material and the azide compound to proceed at a temperature for a length of time sufficient to produce the functionalized nano graphene material. USE - For producing a chemically functionalized nano graphene material (claimed). ADVANTAGE - The process is simple or single-step for large-scale production of soluble or dispersible nano graphene platelets (NGPs) with a high density of functional groups from both pristine nano graphene (p-NGP) and graphene oxide (GO); and provides facile, green, and cost-effective production of functionalized NGPs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for combined production-functionalization process (P2) for manufacturing a chemically functionalized nano graphene material from graphitic material involving dispersing the graphitic material and bi-functional or multi-functional compound in liquid medium to form a suspension, where the graphitic material is selected from natural graphite, artificial graphite, highly oriented pyrolytic graphite, carbon fiber, graphite fiber, carbon nano-fiber, graphitic nano-fiber, meso-carbon micro-bead, graphitized coke, its pre-intercalated versions, its pre-oxidized versions, its pre-fluorinated versions, its pre-halogenated versions, and/or its chemically modified versions; and subjecting the suspension to direct ultrasonication with ultrasonic waves of a desired intensity for a length of time sufficient to produce nano graphene platelets and to enable a chemical reaction to occur between the nano graphene platelets and the compound to produce the functionalized nano graphene material.
