▎ 摘　　要

NOVELTY - A metal matrix nanocomposite is produced by (A) preparing a graphene dispersion comprising multiple discrete graphene sheets dispersed in liquid adhesive resin; (B) bringing the graphene dispersion in physical contact with a solid substrate surface and aligning graphene sheets along a planar direction of substrate surface where graphene sheets are bonded to and supported by substrate surface; (C) depositing a layer of metal or metal alloy having a thickness of 0.5 nm-10 mu m, onto surfaces of aligned graphene sheets to form a layer of metal-coated graphene sheets supported by substrate surface, where metal or metal alloy contains a transition metal, aluminum (Al), magnesium (Mg), tin (Sn), indium (In), lead (Pb), and/or alloy; and (D) separating the layer of metal-coated graphene sheets from substrate surface and consolidating the layer of metal-coated graphene sheets into a metal matrix nanocomposite. USE - Production of metal matrix nanocomposite. ADVANTAGE - The method provides metal matrix nanocomposite that exhibits a combination of exceptional tensile strength, modulus, thermal conductivity, and/or electrical conductivity.

An INDEPENDENT CLAIM is included for producing a metal matrix nanocomposite. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the process for producing oxidized graphene sheets that entails chemical oxidation/intercalation, rinsing, and high-temperature exfoliation procedures.
