Analysis of Band Gap Energy And Refractive Index of Electrospinning Polyacrylonitrile (PAN) Nanofibers

Abstract

Polyacrylointrile PAN was prepared by electrospinning method in normal condition at the room temperature .The PAN nanofibers were investigated by XRD and SEM techniques .Optical properties of the thin film of Polyacrylointrile (PAN) nanofibers were studied by the transmission and absorption spectra at room temperature within the wavelength of (300-700nm) . Optical energy gap Eopt and other parameters were calculated using Tauc relation . The dispersion relationship of refractive index were computed by using Wemple – Didomenico single oscillator model.
