▎ 摘  要

NOVELTY - Producing a multi-layer graphitic laminate, comprises: (a) providing two carbon-based layers comprising graphitic films and graphene layers, where at least one of the graphene layers comprises a sheet of graphene paper, graphene fabric, graphene film, graphene membrane or graphene foam and the graphene comprises pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene and/or chemically functionalized graphene; and (b) laminating at least two of the carbon-based layers and at least one conductive adhesive layer disposed between the carbon-based layers to form the multi-layer graphitic laminate, where the conductive adhesive layer comprises graphene sheets or expanded graphite flakes dispersed in or bonded by an adhesive resin and the graphene sheets or expanded graphite flakes occupy a weight fraction of 0.01-99 wt.%. USE - The process is useful for producing the multi-layer graphitic laminate, where the laminate is useful: in an electronic device; and as an advanced EMI-shielding and thermal management material in microelectronic, photonic and photovoltaic systems. ADVANTAGE - The process: provides the graphitic laminate that exhibits a combination of exceptional thermal conductivity of 1500-1750 W/mK, in-plane electric conductivity of 3000-20000 S/cm, physical density of 1.5-2.26 g/cm3 and mechanical strength unmatched by any material of comparable thickness range; and is cost-effective.
