▎ 摘　　要

NOVELTY - Graphene composite material comprises 50-100 wt.% of graphene and 0.001-50 wt.% of nanomaterials. The other nanomaterials are carbon nanotubes and/or carbon nanofibers. USE - The graphene composite material is useful in 3C and for manufacturing flat displays, LEDs, battery modules, automotives, medical equipments, aerospace, metallurgies and nuclear reactions. ADVANTAGE - The graphene composite material has high purity, excellent heat conductivity, electrical conductivity and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of the graphene composite material comprising preparing a slurry of high concentration lamellar graphite, introducing the slurry into a common paper machine, adding nanomaterials, diluting and filtering the components to obtain wet graphene composite paper with certain thickness, drying the wet graphene composite paper at 25-35 MPa to obtain a graphite composite film and placing the graphite composite film above a high temperature furnace for recrystallization treatment.
