Investigation of optical and dispersion parameters of polyacrylonitrile (PAN) nanofibers fabricated via electrospinning method

Abstract

The current paper deals with the studies of optical properties of Polyacrylonitrile (PAN) nanofibers, as an engineering material with increasing technological attention. The optical properties of PAN nanofibers deposited by the electrospinning technique were investigated. We have introduced the dispersion and optical parameters of PAN nanofibers using a UV-Vis-NIR spectrophotometer. The morphologies of PAN nanofibers were observed by scanning electron microscopy (SEM). The optical energy gap of PAN nanofibers was determined as 3.55 eV. In addition, the optical conductivity of PAN nanofibers was interpreted using the analysis of optical dielectric constants. The obtained results of PAN nanofiber help the desirable property for optoelectronic devices.
