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.

Microwaves are currently used in many fields, including the military, medical, and communication. However, ensuing electromagnetic radiation has seriously threatened human life. Therefore, design of high-performance microwave absorbing materials (MAMs) become an important development direction. Metal-organic frameworks (MOFs) regarded as a bright new star among MAMs with broad application prospects due to their advantages tunable structure, large specific surface area, high porosity, etc . This paper reviews research progress derived from MOFs recent years, preparation methods, properties absorption mechanisms. Finally, problems MOF-derived discussed.

The extensive utilization of high-end wireless electronic equipment in medical, robotics, satellite, and military communications has created a pressing challenge for real-time electromagnetic interference (EMI) control. Herein, piezo-powered self-chargeable supercapacitor (PPSC) architecture based on an iron-doped graphitic nitride (Fe-g-C3N4: FGN) electrode with solid piezoelectrolyte is devised, which can provide controlled EMI shielding through self-charging voltage (SCV). This PPSC device along SCV-controlled also integrates additional features like nanoenergy generation storing capability. results demonstrate that the capable exhibiting piezo-tuned ability up to 669.2 mV under 9.47 N dynamic 180 s. SCV electrostatically modifies causes destructive governs absorption radiation (EMR) controls absorption-dominated 59.2 dB at 500 mV. Additionally, SCV-led electrification unique functional transition from EMR reflector absorber ∼90 Hence, this strategy tailored reflection adjustments could potentially contribute toward advancement stealth technology armaments externally capabilities.
