NOVELTY - The application relates to a heat-conducting wave-absorbing composite film, comprising a reducing graphene layer and MXene nano-sheet layer connected with the reducing graphene layer. The MXene application-sheet layer and the reducing graphene layer form a layered structure of the composite film, the composite film of the layered structure and each layer generated by the micro-pore can make the electromagnetic wave for multiple times of reflection/scattering, achieving good wave absorbing effect, the maximum electromagnetic shielding efficiency of the composite film reaches 105dB; At the same time, each layer of the composite film has excellent heat-conducting performance, so that the heat-conducting coefficient of the whole composite film can reach to 2200W/ (m k)).
