Abstract
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:Rate (3)=3/(3+4)×100   Equation 1wherein Pis a peak intensity of a (101) plane of the rhombohedral graphite layer (3R) based on the X-ray diffraction method, and Pis a peak intensity of a (101) plane of the hexagonal graphite layer (2H) based on the X-ray diffraction method.
