Iron oxide-graphene oxide (Fe3O4-GO) hybrid nanoparticle-nanoplates was synthesized in multistep process for achieving higher performance and synergetic effect of magnetic properties of the Fe3O4 nanoparticles and conductive properties of GO nanoplates. Then, novel multifunctional Fe3O4-GO/PVDF nanocomposite fiber mats were prepared using solution mixing and electrospinning methods. The effect of the Fe3O4-GO contents on the morphological, piezoelectric and electromagnetic microwaves absorption properties of the PVDF nanocomposite fiber mats was investigated. The morphology of the nanofibers was investigated by scanning electron microscope (SEM). Transformation of alpha to beta crystals in fiber nanocomposites was studied using Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction techniques (XRD). The thermal behavior of Fe3O4-GO/PVDF nanofibers were studied by differential scanning calorimetry (DSC) technique. Also, to verify the piezoelectric properties of the Fe3O4-GO/PVDF nanofibers, a piezoelectric properties oscilloscope sensor was used. Microwave absorption performance of the synthesized nanofibers was investigated in the X-band and ku-band. Results demonstrate that the Fe3O4-GO hybrid nanoparticles had a great influence on the alpha to beta phase transformation of the PVDF crystals, piezoelectric response and microwave absorption properties in fiber mats of the PVDF hybrid nanocomposites.
