Lightweight magnetic-carbon nanocomposites with multiple magnetic components are highly desirable for their efficacy in broadband microwave absorption. However, fabricating such composites rationally designed chemical composites, tailored microstructure, and uniformly distributed remains a grand challenge using conventional carbon precursors. Herein, we report the facile fabrication of porous N-doped (Fe3O4@FeCN) Fe/Fe3C/Fe3O4 nanoparticles conjugated microporous polymers (CMPs) as precursor. CMPs have high specific surface area abundant nanoporosity, facilitating efficient loading iron ions uniform growth inside matrix. Notably, Fe3O4@FeCN-2 demonstrates excellent absorption capabilities minimum reflection loss (RLmin) −49.68 dB wide bandwidth 5.72 GHz at matching thickness only 2.0 mm. This outstanding performance is primarily attributed to synergistic effects significantly improved impedance matching, enhanced polarization loss, introduction through embedded nanoporous Moreover, simulation computer technology (CST), shows reduced radar cross section (RCS), RCS values <−10 covering entire frequency band 2–18 angles 30, 60, 90°, demonstrating its great potential applications systems stealth technology. work will inspire development precursors fabricate lightweight precisely controlled structures high-performance

The construction of hollow structures and the incorporation metal nanoparticles have been shown to be two potential approaches achieving high-performance microwave absorption. In this study, a polyhedron material featuring an FeN/Fe-doped carbon matrix was synthesized by acidification corrosion pyrolysis strategy. formation heterojunctions, coupled with design structures, significantly improved dielectric loss capacity material. Furthermore, magnetic not only increased but also enriched mechanisms material, leading overall improvement in loss. Under synergistic effects these factors, exhibited exceptional absorption properties. particular, at thickness 2.3 mm, minimum reflection value FeN/Fe@HC nanocomposite reached -64.5 dB effective bandwidth 5.1 GHz. These results further highlight importance structure atom doping improving performance.
