▎ 摘　　要

NOVELTY - A copper-plated nanoparticle graphene composite material is prepared by taking adding disodium EDTA to 0.08-0.12 mol/L copper(II) sulfate aqueous solution, stirring, obtaining mixed solution, mixing with graphene powder, ultrasonicating for 30-60 minutes, adding reducing agent, reacting, adding sodium hydroxide, standing, precipitating, filtering, washing, and drying at 50-70 degrees C. USE - Method for preparing copper-plated nanoparticle graphene composite material. ADVANTAGE - The method has low impurity content, has small grain diameter, uniform distribution, high bonding strength and has improved electrical performance.
