Abstract:
PURPOSE: A method for producing a low-dimensional carbon-contained composite and a method for producing a carbon block are provided to add a carbon nano tube with point/line contact properties and grapheme with surface contact properties, thereby increasing electric conductivity of a carbon composite. CONSTITUTION: Graphene and a low-dimensional carbon material are added to pitch. The grapheme, the low-dimensional carbon material, and the pitch are uniformly distributed through a post-processing process. Pressing molding of a carbon composite is performed by a press device. A molded product is thermally processed at 150~350 degrees for 2~6 hours. The molded product is carbonized at 1000~1500 degrees after oxidation stabilization. The oxidation stabilization of the molded product is performed under a low temperature for a long time. Therefore, a carbon block with high electric conductivity is manufactured.
