In this study, we fabricated electrically conducting nano (micro) PEDOT non-woven web using the electrospinning technique. Electrospinning of the PEDOT non-woven web was carried out under applying electrical high voltage of 10 to 30 kV to the electrospinning solution. We used 1-propanol or 1-butanol as a solvent and poly(vinyl pyrrolidone) (PVP) as matrix polymer to prepare the electrospinning solution. To investigate the effect of solvent on formation of PEDOT fibers, we changed the solvents or another components and their proportion. Electrochemical capacitor was assembled using one pair of fabricated PEDOT non-woven webs as electrodes by a simple stack method in various kinds of electrolyte solution, where platinum plates were used as current collectors. We measured electrochemical properties of the PEDOT non-woven webs using cyclic voltammetry and charge/discharge experiment, confirming the PEDOT web was electrochemically reduced and oxidized repeatedly. |
