▎ 摘　　要

NOVELTY - Functionalizing carbon material, comprises (a) preparing a first raw material using graphene or thin-graphite, (b) mixing a nitrogen-functional group containing second raw material with the first material to obtain mixture, (c) doping nitrogen-functional group in the first material through thermal plasma treatment by adding the mixture into thermal plasma reactor, and (d) collecting the doped fusion thin-graphite or fusion graphene. USE - The method is useful for functionalizing carbon material (claimed). ADVANTAGE - The carbon material has excellent conductivity and electromagnetic shielding effect.
