The invention relates to the technical field of electronic materials, in particular to a wave-absorbing material, a preparation method of the wave-absorbing material and a mobile phone NFC antenna, the wave-absorbing material comprises wave-absorbing powder and polymer resin, and the wave-absorbing powder is of a two-dimensional sheet structure and is laid and filled in the polymer resin. According to the wave-absorbing material, the wave-absorbing powder is mixed with the macromolecule resin in a tiled filling mode, wave-absorbing materials which are uniform in particle distribution and easy to process into various shapes can be formed, the macromolecule resin plays a role of a filling agent and a binding agent in the wave-absorbing material, the wave-absorbing powder can be uniformly distributed in the wave-absorbing material, and the wave-absorbing effect is improved. The wave-absorbing material has the advantages that the magnetic isolation effect is improved, the wave-absorbing powder can be tightly comb
