Carbon-based materials are considered to be promising candidates for lightweight microwave absorption (MAMs). However, single carbon-based cannot meet the requirements of wide effective bandwidth (EAB) and strong due missing magnetic loss. Combining with via rational design microstructures attends an way achieve high-performance absorption. In this study, core-shell carbon nano-onions@fluorinated boron nitrides (CNOs@F-BNNOs) nanocomposites N-C F-B bridging were obtained by a simple in situ pyrolytic polymerization as well hydrothermal fluorination strategy exhibited excellent properties. Furthermore, results indicate that addition F-BNNOs not only improves polarization loss optimizes impedance matching but also enhances effect, thereby improving electromagnetic wave performance (EWAP). Among these compositions, CNOs@F-BNNOs minimum reflection (RLmin) value -43.23 dB at 17.23 GHz, EAB 10.54 GHz thickness 2.80 mm. Additionally, have thermal conductivity. Therefore, work presents novel approach constructing lightweight, efficient,

In response to the increasing need for high‐performance microwave absorption materials (MAMs), this study introduces a multiaxis electrospinning method synthesizing graphene‐based aerogel microspheres (GAMs) aimed at broadband (MA). The micro/nanostructures and shell configurations of GAMs are effectively regulated controlled establish predictable structure‐properties relationship via establishing equivalent electromagnetic (EM) models. computational simulations results structure–property employed as guidance evaluate effects structural features, like hollow structures multilayered shells. analysis reveals that enhancing cavity optimizes impedance matching promotes MA performance. Utilizing these insights, fabricated (HGAMs) achieve an effective bandwidth (EAB) 8.1 GHz optimal reflection loss −34.8 dB 3.3 mm thickness. Further involving various hierarchical arranged into mono/bilayer arrays investigate group coupling on performance through synergistically absorptive, interferential, resonant attenuation mechanisms. Actual examination using arch HGAM bilayer confirms simulations, achieving EAB 15 thickness 7 mm. Consequently, approach demonstrates promising avenue developing lightweight, nanostructured MAMs suitable advanced applications.

Abstract Deterministic fabrication of highly thermally conductive composite film with satisfying low‐frequency electromagnetic (EM) absorption performance exhibits great potential in advancing the application 5G smart electric devices but persists challenge. Herein, a multifunctional flexible combined hetero‐structured Fe 6 W C‐FeWO 4 @C (FWC−O@C) as absorber and aramid nanofibers (ANFs) matrix was prepared. Driven by an atomic gradient infusion reduction strategy, carbon atoms absorbers can be precisely relocated from shell to core oxometallate lattice, triggering situ carbothermic for customization unique oxometallate‐carbide heterojunctions surface geometrical structure. Such reconstruction process effectively regulates interface electronic structure magnetic configuration, resulting enhanced polarization loss abundant heterointerfaces crystal defects hierarchical endowed coupling interaction, which jointly contributes efficient EM performance. Eventually, optimized FWC−O@C microplate broad bandwidth surpassed entire C band, assembled FWC−O@C/ANFs also performs high thermal conductivity over 2500 % higher than that pure ANFs. These findings provide new insight into affected properties generalized methodological guidance preparing films.
