摘　　要：Metal-backboned polymers with anisotropy microstructures are promising for conductive,optoelectronic,and magnetic functional materials.However,the structure-property relationships governing the interplay between the chemical structure and electromagnetic property of the metal-backboned polymer have been rarely investigated.Here we report a carbon/nickel hybrid from metal-backboned polymer to serve as electromagnetic wave-absorbing materials,which exhibit high microwave absorption capacity and tunable absorption band.The presence of nickel backbones promote the generation of heterogeneous interfaces with carbon during calcination,thereby enhancing the wave-absorbing capacity of the carbon/nickel hybrid.The C/Ni hybrids show a minimal reflection loss of-49.1 dB at 13.04 GHz,and its frequency of the absorption band can be adjusted by controlling the thickness of the absorption layer.
