N2 - In this study, a novel core-shell ternary composite systems containing Fe-Co alloy (Fe-Co) @silicon dioxide (SiO2) @polyaniline (PANI) was prepared by a rational route. The product exhibited high-performance electromagnetic absorption property within the range of 2–18 GHz. Meanwhile, the elements, structure, morphology and electromagnetic wave parameters of FeCo@SiO2@PANI were subsequently detected by XRD, XPS, TEM, SEM and VNA. The maximum absorption of FeCo@SiO2@PANI composite reached −48.6 dB with a layer of thickness only of 1.6 mm and the effective frequency width of absorption was lower than −10 dB reaches 8.4 GHz with the thickness range of 1.6–4.0 mm. In addition, the adding the FeCo@SiO2@PANI composite in the paraffin matrix is only 30 wt%. Consequently, it is believed that the ternary composite materials could be used as an excellent electromagnetic wave absorber with lightweight, thin thickness, broad bandwidth and strong absorption.
