▎ 摘　　要

NOVELTY - Preparation of graphene/metal composite powder comprises ultrasonic dispersing graphene oxide in deionized water to obtain oxidized graphene water solution; mechanical stirring and uniformly dispersing metal powder to oxidized graphene water solution to obtain graphene oxide/metal composite slurry; drying in freeze-drying box to obtain oxidized graphene/metal composite powder; and calcining at high temperature, reducing graphene oxide into graphene/metal composite powder. USE - Method for preparing graphene/metal composite powder. ADVANTAGE - The method uses graphene oxide with good dispersivity in water instead of graphene as raw material, and solves agglomeration problem.
