Modification of graphene with copper particles will make it possible to create a composite that can replace pure copper, primarily in heat dissipation. In this work, the possibility of plasma-chemical production of Cu/graphene composite particles is experimentally demonstrated. The method is simple and easily scalable. The experiment and molecular dynamics simulations were combined to better understand the mechanism of graphene modification by copper particles in a plasma flow. The simulation showed that, depending on the speed and direction of movement of Cu particles in the flow, Cu/graphene nanoparticles of different morphology are obtained. The simulation results are in good agreement with the morphology and properties of the synthesized Cu/graphene composite nanoparticles.
