An Investigation on the Rectifying Characteristics of PVA/Y2O3 Nanofibers
An electrospinning approach was used to synthesize composite nanofibers of polyvinyl alcohol (PVA) doped with different concentrations (2.5, 5, and 10 wt%) of Yttrium Oxide (Y2O3). The XRD diffraction pattern revealed a cubic structure of the prepared nanocomposite. The optical characteristics of p...

| description |
An electrospinning approach was used to synthesize composite nanofibers of polyvinyl alcohol (PVA) doped with different concentrations (2.5, 5, and 10 wt%) of Yttrium Oxide (Y2O3). The XRD diffraction pattern revealed a cubic structure of the prepared nanocomposite. The optical characteristics of pure PVA films and PVA/Y2O3 at different ratios were studied, where the energy gap decreases with the increase of Y2O3 concentration. The morphology and the functional group of the prepared samples were characterized using field emission scanning electron microscopy (FESEM) and Fourier transform infrared (FTIR) spectrophotometry, respectively. Field emission scanning electron microscopy (FESEM) FESEM (images confirm the formation of well-defined nanofibers with variations in fibre diameter as the Y₂O₃ content increases, while FTIR spectra reveal characteristic functional groups associated with both PVA and Y₂O₃. Finally, the current-voltage (I-V) characterization of PVA and PVA/ was measured at room temperature using a Keithley Electrometer, where the results show the non-Ohmic behaviors. Indicating potential applications in electronic and sensing devices.
