Method for preparing layered oriented CNTs/Cu composite material through lost foam assisted sintering

The invention discloses a method for preparing a directional CNTs/Cu composite material through lost foam assisted sintering, and belongs to the technical field of copper-based composite materials. The preparation method comprises the following steps: firstly, carrying out oxidation, sensitization, activation, sex loading and hydrophilic polymer treatment on original CNTs in sequence, so that the CNTs are functionalized, and hydrophilic and magnetic nanoparticles are attached to the surfaces of the CNTs; and dispersing the obtained modified CNTs in polystyrene mother liquor, preparing into a film shape, stacking layer by layer, packaging in a graphite mold, and carrying out hot pressed sintering to obtain the CNTs/Cu composite material. According to the method, the problem that the carbon nanotubes are not uniformly and disorderly distributed in a copper matrix is solved, the electrical, thermal and mechanical properties and the like of the CNTs/Cu composite material can be further improved, and the anisotrop
