Abstract
Provided is a graphite-based carbon material useful as a graphene precursor, from which graphene is easily exfoliated when the graphite-based carbon material is useful as a precursor and from which a highly-concentrated graphene dispersion can easily be obtained. The graphite-based carbon material is a graphite-based carbon material useful as a graphene precursor wherein a Rate (3R) based on an X-ray diffraction method, which is defined by following Equation 1 is 31% or more:Rate(3)=3/(3+4)×100  Equation 1wherein
