▎ 摘　　要

NOVELTY - Composite material comprises a heat conducting layer and a functional wave absorbing layer, where the heat-conducting layer and the functional wave absorption layer are bonded by an agglomerant. The heat conducting layer includes a carbonized wood with an ordered pore structure, and a heat conductive filler loaded in the hole channel of the carbonization wood. The functional wave absorbing layer is a composite functional layer of a composite magnetic material on the light carbon material and/or MXene material. The heat-conducting filler is at least one boron nitride, aluminum oxide, carbon nanotube, graphene or silicon carbide. The light carbon material is at least one of graphene, carbon powder or expanded graphite. The transition metal is scandium, titanium, vanadium, chromium, manganese, zirconium, niobium, molybdenum, hafnium, tantalum, tungsten, X is carbon and/or nitrogen. USE - Composite material with functions of heat conducting and electromagnetic protection for use in a wave-absorbing heat-conducting shielding composition. ADVANTAGE - The composite material has high heat-conducting and wave-absorbing performance; and utilizes the ordered pore canal of the carbonized wood to construct the heat conducting channel, and thus provides high efficiency heat conduction and high efficiency electromagnetic absorption, so as to prolong the service life of the fifth generation (5G)communication core radio frequency device and improve the working efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of composite material with functions of heat conducting and electromagnetic protection. DESCRIPTION OF DRAWING(S) - The diagram shows the overall structure schematic diagram of the composite material with functions of heat conducting and electromagnetic protection for use in a wave-absorbing heat-conducting shielding composition (Drawing includes non-English language text).
