| 제목 | Preparation of Carbon Nanofiber Electrodes Using Cross-linked 6FDA-Durene for Supercapacitors |
| 초록 | Supercapacitor includes EDLC (elctrochemical double layer capacitor), pseudocapacitor, and hybrid capacitor. In this study, EDLC, which stores its charge in the double layers at the interfaces between electrodes and electrolyte, was investigated. To accept electrolyte ions functionally, high specific surface area of the electrodes is essential. Precursor polymer, 6FDA-durene was synthesized with 6FDA(4,4'-(hexafluoroisopropylidene diphthalic anhydride) and durene-diamine(2,3,5,6-tetramethyl-1,3-phenyldiamine). Then, 6FDA-durene was electrospun, cross-linked, stabilized, and carbonized. Finally, the carbon electrode of EDLCs was obtained. Surface cross-linking is used to further increase the specific surface area and porosity of the carbon electrodes. The prepared carbon electrode were characterized by fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Raman spectroscopy, quartz crystal microbalance (QCM) and cyclic voltammetry (CV). |
