| 摘要 |
<p>The invention provides a graphene composite comprising at least a graphene partially exfoliated from a graphite-based carbon material and dispersed in a base material, the graphite-based carbon material having a rhombohedral graphite layer and a hexagonal graphite layer, wherein a Rate of the rhombohedral graphite layer and the hexagonal graphite layer, based on an X-ray diffraction method, which is defined by following Equation 1, is 31% or more: Rate = P3/(P3+P4)x 100.--- (Equation 1) wherein P3 is a peak intensity of a (101) plane of the rhombohedral graphite layer based on the X-ray diffraction method, and P4 is a peak intensity of a (101) plane of the hexagonal graphite layer based on the X-ray diffraction method, the graphene being a crystal of a mean size of 1 00nm or more and formed in a flake-like or sheet-like shape having 10 layers or less. The invention also provides a method of providing a graphene composite. -- -- - - - - -- - - - - -- - - - - - i ~2H(002)[P2] -~ - - --- -- - - - 2H'CIJ4 3R1C '[3</p> |
