▎ 摘　　要

NOVELTY - Producing hydrogen-functionalized graphene-metal composite casting material, comprises (a) preparing graphene powder and metal powder, (b) mixing the prepared graphene powder with prepared metal powder to obtain mixed powder, and (c) increasing the contact area between graphene and metal powder in the mixed powder by adding the prepared mixed powder into a mixer in an inert gas atmosphere, and mixing at a predetermined temperature for a predetermined time. The mixed powder is injected into a hydrogen-functionalization device after flowing the mixed gas mixed in a predetermined volume ratio for the predetermined time, and cooling the injected mixed powder. USE - Method for manufacturing hydrogen-functionalized graphene-metal composite casting material. ADVANTAGE - The method enables manufacture of hydrogen-functionalized graphene-metal composite casting material having excellent dispersibility, with high productivity. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of method for manufacturing hydrogen-functionalized graphene-metal composite casting material (Drawing includes non-English language text).
