enhancement of the pvdf’s piezoelectricity by magnetic-conductive hybrid nanoparticle-nanoplates

Iron oxide-graphene oxide (fe3o4-go) hybrid nanoparticle-nanoplates were synthesized in a 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 and piezoelectric properties of the pvdf nanocomposite fiber mats was investigated. the morphology of the nanofibers was investigated by scanning electron microscope (sem). the transformation of α to β crystals in fiber nanocomposites was studied using fourier transform infrared (ftir) spectroscopy and x-ray diffraction techniques (xrd). also, to verify the piezoelectric properties of the fe3o4-go/pvdf nanofibers, a piezoelectric properties oscilloscope sensor was used. results demonstrate that the fe3o4-go hybrid nanoparticles had a great influence on the α to β phase transformation of the pvdf crystals and piezoelectric response properties in fiber mats of the pvdf hybrid nanocomposites. keywords: pvdf, nanofiber, grapherne, piezoelectricity iron oxide-graphene oxide (fe3o4-go) hybrid nanoparticle-nanoplates were synthesized in a 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 and piezoelectric properties of the pvdf nanocomposite fiber mats was investigated. the morphology of the nanofibers was investigated by scanning electron microscope (sem). the transformation of α to β crystals in fiber nanocomposites was studied using fourier transform infrared (ftir) spectroscopy and x-ray diffraction techniques (xrd). also, to verify the piezoelectric properties of the fe3o4-go/pvdf nanofibers, a piezoelectric properties oscilloscope sensor was used. results demonstrate that the fe3o4-go hybrid nanoparticles had a great influence on the α to β phase transformation of the pvdf crystals and piezoelectric response properties in fiber mats of the pvdf hybrid nanocomposites.
