NOVELTY - The invention claims a three-dimensional heat-conducting wave-absorbing reinforced composite film, comprising a heat-conducting wave-absorbing composite film, wherein the heat-conducting wave-absorbing composite film comprises a graphene layer and MXene layer connected with the graphene the heat-conducting wave-absorbing composite film along the thickness direction is provided with multiple through holes through the upper and lower surface of the heat-conducting wave-absorbing composite film, the through hole is fixed with several diamond particles coated with a graphene The diamond particles coated with the graphene film include diamond particles and a graphene film. In the application, the graphene layer has excellent heat-conducting effect, MXene layer as the reinforcing layer is added to the heat-conducting wave-absorbing composite film, obviously improves the wave-absorbing performance of the three-dimensional heat-conducting wave-absorbing reinforced composite film; the thickness direction of the heat-conducting wave-absorbing composite film is provided with a diamond particle coated with graphene, which improves the longitudinal heat-conducting performance of the three-dimensional heat-conducting wave-absorbing reinforced composite film, but also improves the intensity of the three-dimensional heat-conducting wave-absorbing reinforced composite film.
