Popis: A novel ternary nanocomposite of Fe3O4 functionalized porous biomass carbon decorated by aligned polyaniline (A-PANI/Fe3O4/PBC) was successfully fabricated by hydrothermal and in situ oxidative polymerization. The morphology and structure of the composite was characterized by X-ray diffraction, fourier transform infrared spectra, scanning electron microcopy, transmission electron microscopy, X-ray photoelectron spectra and vibrating sample magnetometer. The microwave absorbing properties of A-PANI/Fe3O4/PBC composite were investigated in the frequency of 2–18 GHz. The results indicated that the A-PANI/Fe3O4/PBC composite possess excellent microwave absorbing performance, and the minimum reflection loss can be up to −44.8 dB at 10.67 GHz, effective absorbing bandwidth (RL
