A composite material and a method for producing the same

Abstract

The application provides a composite material and a preparation method thereof. The composite material comprises flower-shaped molybdenum disulfide and sheet-layer reduced graphene oxide; the flower-shaped molybdenum disulfide has a three-dimensional hierarchical structure formed by assembling a plurality of flower-shaped molybdenum disulfide sheet structure units and / or layer structure units; the flower-shaped molybdenum disulfide is loaded on the surface of the reduced graphene oxide sheet layer and / or embedded in the gap between the reduced graphene oxide sheet layers; and the plurality of reduced graphene oxide sheet layers are overlapped with each other to form a three-dimensional skeleton network, which can support and disperse the flower-shaped molybdenum disulfide and form continuous heat conduction paths and electric conduction paths in the composite material. The flower-shaped molybdenum disulfide in the composite material can enhance the multiple reflection, scattering and interface polarization loss of electromagnetic waves, and the reduced graphene oxide can provide a three-dimensional skeleton network, so that the composite material can realize the synergistic improvement of the wave absorption performance and the heat conduction performance, and thus the composite material simultaneously has excellent wave absorption performance and heat conduction performance.
