GRAPHITE-BASED CARBON MATERIAL WHICH IS USED AS GRAPHENE PRECURSOR, GRAPHENE DISPERSION AND GRAPHENE COMPOSITE INCLUDING SAME, AND METHOD FOR PRODUCING SAME

摘要

Provided is a graphite-based carbon material which readily exfoliates into graphene when used as a graphene precursor and from which a high-concentration graphene dispersed solution can be obtained easily. In this graphite-based carbon material which is used as a graphene precursor, Rate (3R) defined by Formula 1 by X-ray diffraction analysis is 40% or more.Rate(3R)=P3/(P3+P4)×100 (Formula 1)P3 is the peak intensity of plane (101) of a rhombohedral graphite layer (3R) by X-ray diffraction analysis, and P4 is the peak intensity of plane (101) of a hexagonal graphite layer (2H) by X-ray diffraction analysis.
