dc.description.abstract |
The design of composites rich heterogeneous interfaces to enhance interfacial polarization is an effective way to boost electromagnetic waves (EMW) absorption performance. In this work, multi-component electromagnetic ZnFe2O4/Fe/Fe4N/N-doped carbon (ZnFe2O4/Fe/Fe4N/N-C) composites were successfully fabricated by carbonization of core/shell/shell ZnFe2O4 @PDA@PPy precursors at 800 °C under a N2 atmosphere. The ZnFe2O4/Fe/Fe4N/N-C composites exhibit excellent low-frequency EMW absorption performance: the effective absorption bandwidth reached 8.41 GHz (3.57–11.98 GHz), covering the entire C-band (4–8 GHz) and X-band (8–12 GHz) at a thickness of 4.5 mm with a minimum reflection loss (RLmin) of −36.13 dB at 4.54 GHz. The excellent property was attributed to the abundant heterogeneous interfaces in the ZnFe2O4/Fe/Fe4N/N-C composites with maximized polarization loss. Further, magnetic loss were enhanced by the introduction of Fe4N. This work demonstrates that the creation of heterogeneous interfaces via adding extra components is an effective strategy in the design of efficient low-frequency EMW absorbers. |
