In this work, EDC@Fe3O4 nanocomposite wave-absorbing materials were obtained by using egg as a precursor and SiO2 templates to prepare porous structures of egg-derived carbon, followed simple reflow calcination process. The microwave absorption properties show that the magnetic content enhances loss composite material, while abundant defects voids on surface carbon form network extends transmission path electromagnetic wave.The synergistic effect Fe3O4 optimizes impedance matching material improves its attenuation ability. As result, nanocomposites exhibit excellent properties. best sample at 9.12 GHz with strongest reflection (RLmin) -54.19 dB matched thickness 2.46 mm, effective bandwidth (EAB) value 5.68 2.03 mm. study, biomass-based lightweight, thin thickness, wide bandwidth, high capacity is designed prepared novel strategies, are shown have absorptive composites light weight, strong ability, elucidated mechanism nanocomposites.
