PREPARATION METHOD FOR EDGE-FUNCTIONALIZED GRAPHITE VIA MECHANIC-CHEMICAL PROCESS USING LOW GRADE GRAPHITE AND THE GRAPHINE NANO-PLATE MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing edge-functionalized graphite with a high doping ratio of a heteroatom while using low grade graphite with low purity, to a manufacturing method of graphene nanoplate, and to the graphene nanoplate manufactured therefrom. The method is capable of mass-producing with a simple and economic manufacturing process, increasing economic feasibility by using low grade graphite with a large average particle size and low contents of a carbon element regarding a raw material, and manufacturing edge-functionalized graphene nanoplate with a significantly high doping ratio of a heteroatom in comparison to the use of the conventional finely pulverized graphite.
