The Fe3O4/PANI rod/rGO nanocomposites were prepared by a new synthesis process, and their microwave absorbing properties were further evaluated. Taking advantage of the synergistic effects of the different components in the nanocomposites and the merits of the proposed synthesis strategies, the Fe3O4/PANI rod/rGO nanocomposites showed excellent microwave absorption performance, especially for obtaining giant absorption bandwidth (ca. 14.6 GHz, <− 10 dB). The work does not only confirm the formation of Fe3O4/PANI rod/rGO nanocomposites with wide absorption frequency range, strong absorption property and lightweight, but also provide a new synthesis process of electromagnetic wave absorbents for large-scale production.
