Carbon nanotube reinforced copper-based composite foam electromagnetic shielding plate

The utility model relates to the field of metal foam, in particular to a carbon nanotube reinforced copper-based composite foam electromagnetic shielding plate, which comprises a foamed copper substrate. The at least one hollow cavity is located in the copper substrate, and the outer layer of the hollow cavity is wrapped with a silver plating layer; the carbon nanotubes are uniformly embedded and distributed in the copper substrate; according to the carbon nanotube reinforced copper-based composite foam electromagnetic shielding plate provided by the utility model, the carbon nanotube with excellent wave absorbing performance is added into the light open-cell metal foam copper with diamagnetism and conductivity, so that the performance coupling effect among the components of the composite material is excited; the excellent comprehensive performance such as electromagnetic shielding, heat dissipation and impact resistance buffering is obtained, and the strong requirement of the current electromagnetic shieldin
