Fabrication and physical properties of conductive polyacrylonitrile-polyaniline derivative fibers

Spinning solutions were prepared by dissolving polyacrylonitrile (PAN) and sulfonated polyaniline (SPAN) in methyl sulfoxide (DMSO) solution. Polyacrylonitrile-sulfonated polyaniline fibers were fabricated by wet spinning method. The fibers were elongated more than 5 times during the spinning process. All of the fibers are conductive without additional acid doping process. The characterization of fibers has been studied by XRD, electrical conductivity, and tensile properties.
