Abstract Recently, the design and development of efficient microwave absorbents by facile engineering approaches have attracted much attention. Particularly, some unique structures caused cross‐scale are promising in enhancing absorbing capability toward irradiation. Herein, strategy is implemented to enhance electromagnetic wave absorption performance polymetallic sulfides (PMS). In PMS, dipole polarization unit optimized, distribution electronic states improved doping Ti atoms; Meanwhile, MS/M 3 S 4 homogeneous hetero‐phases interfaces constructed PMS using a phase separation strategy; conductivity modulated addition acetylene black (ACET). The synergy leads significant enhancement (MA) PMS/ACET composites. optimal reflection loss value Ti‐LES with 10% ACET reaches −55.49 dB effective bandwidth 6.73 GHz. 17.5% ACET‐conditioned Ti‐HES achieves −37.2 at low frequency 4.8 This study not only provides novel for new broadband MA materials but also validates idea multi‐scale synergistic optimization materials.

Abstract The explode development of global automation and digitization brings increasing electromagnetic radiation, threatening information security health. Biomass wave-absorbing materials stand out among massive absorbers due to their green environmentally friendly features, yet remains severe challenge in equilibration between impedance matching efficient loss ability. Herein, this work innovatively used waste bark which amounts up 400 million cubic meters generated from forest as carbon precursor. FeCo@C nanocomposites derived FeCo-MOF precursor are introduced on the surface bark-derived pore using vacuum impregnation carbonization methods, tree porous (TPC)/FeCo@C composites successfully fabricated. unique hierarchical structure composed three-dimensional (3D) parallel yolk-shell favors optimizing prolonging attenuation paths microwaves. Additionally, introduction can promote interface polarization loss, well enhance synergistic effects dielectric-magnetic losses. Multiple structural coupling endow TPC/FeCo@C composite attractive absorbing optimized TPC/FeCo@C-5 exhibits a minimum reflection (RL min ) − 61.04 dB effective bandwidth (EAB) 7.25 GHz at thickness 2.64 mm, is superior most biomass-based absorbers. Apparently, presents valuable concept for secondary utilization discarded domain microwave absorption, significant achieving energy saving environmental protection addressing pollution.
