A new form of nanofiber web electrode has been prepared for EDLCs useing eletrospun MWNT grafting para-Poly(ether ketone)-based carbon nanofibers. The specific ranges of apply voltage, concentration of MWNTs-g-p-PEK solutions, and TCD are charged to obtain optimizing conditions of the nanofiber webs. The nanofiber webs are stabilized by fitting temperature and then carbonized at 1000℃under N2 conditions. The surface Characteristics of the nanofibers before and after stabilization and carbonization are evaluated by FT-IR, XPS, and XRD. The resultant diameter distribution and morphologics are also studied by AFM and SEM. The electrochemical properties of the electrodes and the capacitive behaviors of the resulting EDLCs are systematically studied using CV and ac impedance tests. |
