Abstract Electromagnetic pollution protection and military stealth technologies underscore the urgent need to develop efficient electromagnetic wave‐absorbing materials (EWAMs). Traditional EWAMs suffer from single absorption loss mechanisms, poor impedance matching, weak reflection loss. To date, combining dielectric with magnetic in have proven be an effective approach enhancing performance. The structural design of composites plays a pivotal role improving matching attenuation waves. It is widely regarded as one principal methods for fine‐tuning parameters response mechanisms. Among these, carbon become research hotspot due their magnetoelectric synergistic effects versatile microstructure design. Herein, principles wave terms both mechanism are outlined. progress on core–shell, skeleton, hollow structure carbon/magnetic composite summarized. synthesis methods, properties, mechanisms these structures described detail. Finally, limitations discussed, possible solutions proposed, future development directions envisioned.

Heterointerface between Carbon Nano-Onions and Fluorinated Boron Nitride Nanostructures for Improved Microwave Absorption Properties

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,
