Abstract

A ternary composite material FeCo@SiO₂@PPy with high-performance electromagnetic absorption have been successfully synthesized and characterized. In this paper, the components, structure and morphology of the FeCo@SiO₂@PPy have subsequently tested by XRD, TEM and SEM. The electromagnetic wave parameters of the composite was detected by the vector network analyzer (VNA). The reflection loss (R_L) of FeCo@SiO₂@PPy composites reaches −65.17 dB with the thickness of 2.1 mm at 16.48 GHz and the absorption frequency bandwidth R_L -10 dB was up to 6.8 GHz (10.4 GHz–17.2 GHz) with the layer of 2.5 mm. The absorption frequency bandwidth lower than −10 dB is up to 13.12 GHz with the range of thickness from 2.1 to 5.0 mm.
