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 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.
