Abstract Optimization of components and micromorphology regulation are shown to be effective in boosting electromagnetic wave absorption (EMWA). One approach achieve this enhancement is by utilizing the polarization effects heterogeneous interfaces. Herein, NiSe 2 ‐CoSe @C@MoSe composites derived from NiCo‐MOF‐74 fabricated via a facile selenization reaction subsequent hydrothermal method. By varying mass ratios @C MoSe , series with hierarchical flower‐like core–shell structures obtained. The EMWA properties display trend initially increasing then decreasing content . Interestingly, when ratio 3:2, minimum reflection loss (RL) value −50.10 dB an bandwidth (RL< −10 dB) can reach 4.80 GHz (13.20–18.00 GHz). remarkable capability ascribed synergy conductive loss, suitable impedance matching. This work establishes new pathway for synthesis transition metal dichalcogenides‐based composites, which hold great promise as high‐performance materials applications.

Abstract Broadband electromagnetic (EM) wave absorption materials play an important role in military stealth and health protection. Herein, metal–organic frameworks (MOFs)-derived magnetic-carbon CoNiM@C (M = Cu, Zn, Fe, Mn) microspheres are fabricated, which exhibit flower-like nano–microstructure with tunable EM response capacity. Based on the MOFs-derived CoNi@C microsphere, adjacent third element is introduced into magnetic CoNi alloy to enhance performance. In term of broadband absorption, order efficient bandwidth (EAB) value Mn > Fe Zn Cu microspheres. Therefore, CoNiMn@C hold outstanding EAB can reach up 5.8 GHz (covering 12.2–18 at 2.0 mm thickness). Besides, off-axis electron holography computational simulations applied elucidate inherent dielectric dissipation loss. Rich heterointerfaces promote aggregation negative/positive charges contacting region, forming interfacial polarization. The graphitized carbon layer catalyzed by CoNiMn core offered mobility path, boosting conductive Equally importantly, coupling observed strengthen responding behaviors. This study provides a new guide build regulating ternary alloy.

Abstract Ultra‐wideband microwave absorbing (MA) materials covering the low‐frequency range (2–6 GHz) are highly desirable in civil and military fields. These can be fabricated based on design of electromagnetic meta‐structure. Herein, a structural‐functional‐integrated ultra‐wideband SiO 2 fiber reinforced cyanate ester (CE) MA composite an situ‐grown graphene meta‐nanointerface layer (GrMI) (SiO 2f /GrMI/CE) is reported. The relationship between periodic structure nano‐interface performance discussed through experiments simulations. results show that /GrMI/CE with thickness 8.78 mm exhibits effective absorption bandwidth 15.46 GHz (2.54–18 GHz). Remarkably, reflection loss remains basically unchanged upon increasing incident angle from 5° to 50°. Additionally, GrMI load‐bearing constituent, which increases interfacial shear stress CE by ≈210% contributes achieving composites ultra‐high flexural strength (552.7 MPa). excellent performances ensure suitable for use as skin stealth aircraft other facilities. work provides novel pathway thinner, wider, lighter, stronger components.
