Abstract
We use plasma method syntheisized Carbon coated copper nanoparticles 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.
