▎ 摘　　要

NOVELTY - Producing hydrogen-functionalized graphene-aluminum composite, comprises (a) mixing graphene powder with aluminum powder in a predetermined ratio to prepare graphene aluminum mixed powder, (b) adding the prepared graphene aluminum powder into a mixer in an inert gas atmosphere, and mixing at a predetermined temperature for a predetermined time, (c) introducing the prepared aluminum powder mixture into a hydrogen functionalization device in which an internal temperature is lower than a melting point of the aluminum powder, and (d) cooling the injected aluminum powder after flowing mixed gas into the device. USE - The method is useful for producing hydrogen-functionalized graphene-aluminum composite casting material. ADVANTAGE - The method enables manufacture of hydrogen-functionalized graphene-aluminum composite cast material having excellent dispersion degree and physical properties. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for producing hydrogen-functionalized graphene-aluminum composite (Drawing includes non-English language text).
