Carbon aerogels were used an electrode of electrical double layer capacitor. Also cabon nanofibers were used an electrode of EDLC. In this work, porous carbon nanofiber/aerogel composites were prepared by electrospinning blend solutions of polyacrylonitrile(PAN) and poly(methyl methacrylate)(PMMA) added carbon aerogel in N,N-dimethylformamide(DMF). The morphology of carbon composites were investigated using scanning electron microscope(SEM) and transmission electron microscope(TEM). The surface area and pore size of carbon composites were measured by BET. Electrochemical property of carbon composites as electrodes were investigated by three electrode system. |
