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.

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.
