Abstract

See full text

A composite lubricating material including at least a graphite-based carbon material and/or graphene-like graphite exfoliated from the graphite-based carbon material dispersed in a base material. The graphite-based carbon material is characterized by having a rhombohedral graphite layer (3R) and a hexagonal graphite layer (2H), wherein a Rate (3R) of the rhombohedral graphite layer (3R) and the hexagonal graphite layer (2H), based on an X-ray diffraction method, which is defined by following Equation 1 is 31% or more:

description='In-line Formulae' end='lead'Rate (3R)=P3/(P3+P4)×100   Equation 1description='In-line Formulae' end='tail'

wherein P3 is a peak intensity of a (101) plane of the rhombohedral graphite layer (3R) based on the X-ray diffraction method, and P4 is a peak intensity of a (101) plane of the hexagonal graphite layer (2H) based on the X-ray diffraction method.
