Electrospun PEDOT Nanofibers for Supercapacitor Electrode |
| 초록 |
In this study, electrically conducting poly (3,4-ethylenedioxythiophene) (PEDOT) nanofiber nonwoven web with large surface area was fabricated by the coaxial electrospinning technique. The oxidant solution including poly (vinyl pyrrolidone) was spun through the core nozzle and at the same time the monomer solution was spun through the shell nozzle. Polymerization of PEDOT was carried out at 70℃ for about 30 minutes and the resulting PEDOT nanofiber was washed with methanol and dried. The PEDOT nonwoven web could be applied as the electrode of electrochemical supercapacitor by simple stack method, where metal plates were used as the current collector. We measured the electrochemical charge and discharge behavior and stability of the supercapacitor, showing relatively high specific discharge capacitance and stable charge/discharge behavior upon repeated cycles. |
