Ni-Co/PC composite is prepared by introducing metal Co element with Ni-MOF/PC as precursor. Then a series of Ni-Co bimetal/PC composites are prepared by polyaniline coating, oxidation reaction, and vulcanization reaction. It is found that vulcanization reaction was the best path for the electromagnetic wave absorption performance of the product. The minimum reflection loss (RLmin) of NiCo2S4/PC composite reaches - 67.81 dB at the sample thickness of 2.6 mm, and the maximum effective absorption bandwidth (EAB) reaches 6.16 GHz when the sample thickness is 2.1 mm. NiCo2S4/PC composite is an ideal electromagnetic wave absorber due to its excellent electrical conductivity, rich surface, and high attenuation capability.
