Abstract
Wave-absorbing materials in the form of a nickel-carbon composite that includes a plurality of modified carbon particles, where each of the modified carbon particles includes a nickel nanoparticle core and a carbon layer wrapped on a surface of the nickel nanoparticle core; and a plurality of the modified carbon particles form an octahedral structure. When a high-frequency microwave interacts with the nickel-carbon composite, the composite has a stronger magnetic loss performance due to various magnetic loss characteristics such as natural resonance and eddy current loss of the magnetic nickel nanoparticles. In addition, the carbon layer, as a shell layer, can provide a directional electron migration path in a special octahedral space structure to construct a conductive network.
