▎ 摘  要

NOVELTY - Preparing chromium-plated graphite/copper composite powder, comprises (i) adding chromium solution of graphene oxide solution, carrying out chemical plating chromium and plating chromium graphene mixed solution; (ii) adding copper powder to the chromium-plated graphene mixed solution, dispersing uniformly, and adding hydrazine hydrate to perform the reduction reaction; and (iii) centrifuging the mixed solution, washing, and drying the precipitate to obtain chromium-plated graphene/copper composite powder. USE - The method is useful for preparing chromium-plated graphite/copper composite powder. ADVANTAGE - The composite powder has uniform texture; has high strength and electrical conductivity.
