Surface modulation strategies have spurred great interest with regard to regulating the morphology, dispersion and flexible processability of materials. Unsurprisingly, customized surfaces is primed offer a route control their electronic functions. To regulate electromagnetic wave (EMW) absorption applications by surface engineering an unmet challenge. Thanks pyrolyzing surface-anchored metal-porphyrin, here we report on four-nitrogen atoms-confined single metal site nitrogen-doped carbon layer (sM(N4)@NC, M = Ni, Co, Cu, Ni/Cu) (sM=single metal; NC= layer) that registers absorption. Surface-anchored metal-porphyrins are afforded attaching them onto polypyrrole via prototypical click reaction. Further, sM(N4)@NC experimentally found elicit identical dipole polarization loss mechanism, overcoming handicaps conductivity loss, defects, interfacial among current EMW absorber models. Importantly, exhibit effective bandwidth 6.44 reflection −51.7 dB, preceding state-of-the-art carbon-based absorbers.

Abstract Despite considerable efforts to tune the morphology and composition from macroscopic level nanoscale of electromagnetic wave‐absorbing materials (EWMs), achieving strong wide‐bandwidth absorption under a temperature‐variant environment remains extremely difficult due temperature‐sensitive electromagnetic‐absorbing mechanisms that involve dipole polarization conductive loss. Here, by integrating highly carbon nanotubes (CNTs) networks temperature‐stable silicon nitride (Si 3 N 4 ) protective layer, CNTs/amorphous carbon@Si (C‐CNT‐Si porous foam composed sandwich‐like Si /C‐CNT/Si strut, which exhibits excellent temperature‐insensitive properties room temperature 600 °C, is demonstrated. To be specific, value minimum reflection loss always lower than −50 dB, effective absorbing bandwidth covering whole X band throughout thickness range 4.8–6.1 mm achieved. The superior property synergistic effects irregular derived lattice vacancies heterogeneous interface, slightly increased decreasing carrier mobility, increasing concentration rising environment.
