Electrically Conductive PEDOT-PSS/PAN Composite Fibers Prepared by Wet Spinning

Abstract:

The composite conductive fibers based on poly (3,4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT-PSS) blended with polyacrylonitrile (PAN) were prepared via a conventional wet spinning process. The influences of PEDOT-PSS content on the electrical conductivity, thermal stability and mechanical properties of the composite fibers were investigated. The fiber with 1.83 wt% PEDOT-PSS showed a conductivity of 5.0 S/cm. The breaking strength of the fibers was in the range of 0.36-0.60 cN/dtex. The thermal stability of the PEDOT-PSS/PAN composite fibers was similar to but a slightly lower than the pure PAN. The XRD results revealed that both pure PAN and the PEDOT-PSS/PAN composite fibers were amorphous phase, and the crystallization of the latter was lower than the former.
