In this paper, we designed a core@double-shell nanostructure to enhance the electromagnetic wave absorption performance of hybrid nanospheres. Herein, the core@double-shell structured Fe3O4@polyaniline@MnO2 nanospheres were successfully prepared by a facile solvothermal process and in situ polymerization methods. The morphology, structure, magnetism and microwave absorption properties were studied. The results reveal that the FPM nanospheres exhibit extraordinary microwave absorbing performance compared to those of either Fe3O4 or Fe3O4@polyaniline nanospheres. The minimum reflection loss of the FPM nanospheres is − 14.7 dB at 15.76 GHz with the thickness of 3.5 mm, and the corresponding effective absorption bandwidth can reach 4.75 GHz. The perfect EMW absorption of nanospheres can be ascribed to multi-interface polarization, multiple reflections and good impedance matching originated from the core@double-shell nanostructure. In this work, the Core@Double-shell structured Fe3O4@polyaniline@MnO2 nanospheres were successfully prepared by a facile solvothermal process and in-situ polymerization methods. The Fe3O4@Polyaniline@MnO2 nanospheres exhibit extraordinary microwave absorbing performance, which is ascribed to multi-interface polarization, multiple reflections, and good impedance matching originated from the core@double-shell nanostructure.
