Preparation of Alignment Nanofibersfrom Polyaniline/polystyrene Blend by Electrospinning Technique

Abstract

Electrospinning method is important technique to prepare aligned nanofiber Materials . Oriented nanofibers of solution PS mixed with PANI-DBSA conducting polymers solution were prepared by electrospinning process. PANI-DBSA/PS nano composite are characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). X-ray diffraction showed semi-crystalline peaks and the grain size about 40 nm. SEM measurements reveal that the prepared samples are fibers in shape and uniformly aligned over the surface of the substrates. The average diameter of nanfibers is about 70 nm. The composite nanofibers shows good conductivity but use of PS as polymeric plasticizer in lowers the electrical conductivity as compare to pure PANI.DBSA.
