• Carbon coated copper nanoparticles
• Antioxidant
• Conductivity

Ultra-fine carbon coated copper nanoparticles was syntheisized using plasma method The structure, size distribution and phase composition of the particles were analysised by TEM, XRD and DSC. Meanwhile, The conductivity of carbon-coated copper nanoparticles were measured. Results show that Carbon coated copper nanoparticles were core-shell structure for the copper core inside, the multi carbon layer outside, around the copper core is graphite-like carbon and far away from the copper core is amorphous carbon. While carbon-coated copper nanoparticles at room temperature and high temperatures have shown good oxidation resistance; The conductivity of carbon-coated copper nanoparticles with metal content increases and when the copper content is 80% the conductivity jump.
