    • Abstract

       

      Iron oxide (Fe$_3$O$_4$)/reduced graphene oxide (rGO)/polyvinylpyrrolidone (PVP) nanocomposite films with varying iron weight percentages were prepared by electrospinning spray method on glass, aluminium foil and Si (100)substrate. The size of Fe$_3$O$_4$/rGO/PVP composite particles varied between 0.75 and 1.35 ${\mu}$m on the surface of the graphene sheet. The diffraction peaks at 36.77°, 47.06°, 52.98° and 61.34° confirmed the plane (311), (400), (422) and(440) of the Fe$_3$O$_4$ crystal lattice, respectively. The broad peaks around 26.6° and 43.47°correspond to the planes (002) and (102) for the rGO sheet in the Fe$_3$O$_4$/rGO/PVP nanocomposite films. The defect parameter, $I_D$/$I_G$ ratio varied from 0.17 to 0.34 with 15 and 25wt% Fe$_3$O$_4$ content, respectively, indicates the decreasing of defects in the Fe$_3$O$_4$/rGO/PVP network. The minimum value of $E_{corr}$ and $I_{corr}$ are 0.18 V and 4.76 ${\mu}$A, respectively.
