Abstract

Novel Ni0.5Zn0.5Fe2O4 (NiZn-ferrite)/Polyaniline (PANI) nanocomposites with NiZn ferrite nanoparticles on the surface of PANI nanofibers were successfully prepared by hydrothermal method. The composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), and UV–vis spectra. The results indicate that the PANI nanofibers (80nm in thickness) are attached by NiZn ferrite nanoparticles. Compared with pure PANI, the thermal stability of composites is improved clearly. The NiZn-ferrite/PANI nanocomposites exhibit ferromagnetic behavior with high saturation magnetization (Ms=43.7emu/g) and coercivity (Hc=138.7Oe) at room temperature. The microwave absorption properties of these composites were measured, and the absorption bandwidth with reflection loss below −10dB is up to 5GHz. The composites could further extend the potential application in microwave absorption and electromagnetic interference shielding fields.
