Abstract: The present study is based on the processing of polyaniline fibers by electrospinning using polyethylene oxide as a stabilizing agent for textile fiber. Polyaniline was doped with camphorsulfonic acid in different percentages to evaluate its influence on the electrical conductivity. In this study, fibers were made from a solution of polyethylene oxide and polyaniline. Chloroform was used as solvent for these polymers. The obtained fibers were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and electrical conductivity. The obtained membranes have been twisted to obtain a yarn having a diameter of (»481 mm), the degree of crystallinity corresponds to a semicrystalline material and their conductivity was similar to semiconductor behavior (range).

Keywords: Fibers, electrospinning, polyaniline, conductivity, doped.
