▎ 摘　　要

NOVELTY - Producing graphene nanocomposite powder comprises (a) charging a metal wire into a mixed solution in which graphene oxide is dispersed; and applying energy to the metal wire charged in the mixed solution to electrically explode the metal wire and the graphene oxide reacting with each other to form a nano powder containing a metal or a metal oxide. The step (b) comprises (b1) forming a reduced graphene oxide in which the reduction and defect healing of the graphene oxide is made due to the explosion of the metal wire, and (b2) forming composite structure by combining nanopowder with metal or metal oxide and the reduced graphene oxide. USE - The method is useful for producing graphene nanocomposite powder. ADVANTAGE - The method produces graphene nanocomposite powder having excellent mechanical/physical properties in short period of time; and is economical. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for producing graphene nanocomposite powder (Drawing includes non-English language text).
