<p>The present invention relates to a manufacturing method of graphene nanopowder. According to the present invention, provided are a method for manufacturing graphene nanopowder in quantity and graphene nanopowder manufactured by the manufacturing method, thereby using a ball milling process, inserting graphite powder and a solvent comprising carbonate and a hydroxyl group together so as to induce an oxygen functional group in quantity, to widen the interlayer spacing, and to have the nano-size particle surface area. Therefore, graphene oxide can be manufactured with a simple method and excellent economic effects using a ball milling process, which is not required for unnecessary additional processes such as acid cleaning or the like, as well as being eco-friendly by solving environmental pollution problems caused by use of chemicals in comparison with a method of chemical exfoliation which is the conventional manufacturing method of graphene oxide. In addition, graphene powder with induction of an oxygen functional group in quantity, widening the interlayer spacing, and the nano-size particle surface area can be manufactured by inserting graphite and a solvent comprising carbonate and a hydroxyl group together in a ball milling process.</p> |
