“…Particle size may have an impact on both the exchange and natural resonances, which could explain these phenomena. Generally, natural resonance occurs at low frequency (2–8 GHz) and exchange resonance occurs at high frequency (16–18 GHz). , The results indicate that smaller particles could possess a higher natural resonance, and larger particles result in a higher exchange resonance.…”

Developing lightweight hybridized nanomaterials with appropriate components and controllable microstructures for high-performance electromagnetic wave (EMW) absorption is highly desired in the applications of EMW pollution protection, and electromagnetic wave interference stealth yet remains a great challenge. Here, a type of FeNi nanoparticle-decorated carbon nanotubes (CNTs) with diverse morphologies is synthesized via an economic one-pot hydrothermal process. Systematic research has been done to determine the influence of the iron−nickel ratio and alkaline conditions on the microstructures of the hybrid nanomaterials and their EMW absorption capabilities. It is noteworthy that an effective bandwidth of 4.2 GHz and a remarkable microwave absorption ability of −59.80 dB at 8.5 GHz were attained, which is attributed to the improved impedance matching and microwave absorption capability by the inherent conductivity of CNTs, the magnetic loss capability of the FeNi 3 nanoparticles, and the multiple interfacial polarizations and multiple reflections. The facile, controllable, and cost-effective fabrication approach integrates with the performance of the hybrid CNT/FeNi 3 nanocomposites, providing an effective strategy for high-performance electromagnetic wave absorption materials.

“…At present, many MoS 2 -based microwave absorbing materials have the characteristics of strong absorption, but the wide band is still to be developed Many studies have shown that hollow microspheres, hollow fibers, porous structures, core–shell structures, etc., reduce the material density, enhance the multiple reflection, and improve the absorption performance. − Therefore, the design and preparation of new wave absorbing materials with multicomponent composites, multilayer structures, and complex microstructures and the study of various wave absorbing mechanisms are also potential development directions in the future. …”

Molybdenum disulfide (MoS2), as a two-dimensional material, has a potential application prospect in microwave absorption, electromagnetic shielding, energy storage, electrochemistry, and other fields due to its unique structure, excellent electrical conductivity, abundant surface area, and good mechanical strength. In this paper, the microwave absorbing properties of MoS2-based composites are reviewed objectively, and the recent research achievements and progress in dielectric loss type and magnetic loss type composites are summarized. Then, the microwave absorption mechanism of MoS2-based composites is systematically analyzed in terms of dielectric loss and magnetic loss. At the same time, the application of MoS2-based microwave absorbing materials in current social needs is summarized including military radar stealth and civil electronic communication. In addition, the challenges and bottlenecks in the future development of microwave absorber materials are also presented.

Metal single‐atoms implanted on nitrogen‐doped carbon matrices (M‐NxCs) can effectively adjust local surface electrons and polarization relaxation through coordination structures to significantly enhance the electromagnetic wave (EMW) absorption properties of the materials. However, the precise construction of the geometric and electronic structures of metal single atoms and the discovery of the structure‐absorption relationship at the atomic level confront a huge challenge. Herein, this work summarizes the latest progress in metal single‐atom engineering of EMW absorbing materials via a comprehensive analysis of M‐NxCs in terms of design principles, modulation strategies, and structure‐performance correlations. Subsequently, it highlights the recent progress of several typical M‐NxCs as the EMW absorbing materials, aiming to achieve a complete understanding of the physical effects and atomic‐level absorption mechanisms. Finally, current key challenge and future directions of M‐NxCs are presented by focusing on the electromagnetic functional materials. This work provides new insights for the development of atomically dispersed absorbing materials for efficient electromagnetic response functionalities.
