Description
Summary:[Display omitted] •Sandwiched MXene/Ferrite@C hybrids have been successfully obtained.•Enhanced interfacial polarization process and improved impedance matching.•Strong electromagnetic absorption of −45.5 dB at a thickness of only 1.6 mm. Sandwiched MXene/Ferrite@C (Ti3C2Tx/Fe3O4@C) hybrids have been successfully obtained by assembling MXene with Fe3O4@C nanoparticles derived from Fe-MOFs. The MXene/Ferrite@C hybrids achieved an excellent microwave absorption performance with a RLmin of −45.5 dB, an effective absorbing bandwidth of 3.5 GHz and a thin thickness of 1.6 mm. Therefore, the sandwiched MXene/Ferrite@C hybrids are expected to be powerful candidates for high performance electromagnetic microwave absorbers.
