Electrically conducting nano (micro) poly(3,4-ethylenedioxythiophene) (PEDOT) fiber non-woven web was fabricated using the electrospinning technique by applying high voltage of 10 to 30 kV to the electrospinning solution. To investigate the effects of various conditions on formation and properties of PEDOT fiber non-woven web, we changed the solvent or other components and their concentrations. We used 1-propanol or 1-butanol as a solvent and poly(vinyl pyrrolidone) (PVP) as a matrix polymer to prepare the electrospinning solution. The electrical conductivity of the electrospun PEDOT non-woven web was as high as 7.5 S/cm when 1-propanol was used as the solvent. Electrochemical capacitor was assembled using one pair of the PEDOT non-woven webs as the electrodes by a simple stack method, where metal plates were used as current collectors. We observed the electrochemical charge and discharge behavior of the capacitor, confirming that the PEDOT non-woven web can be used as the electrode for flexible electrochemical capacitor.
