| Abstract: | This work focuses on preparations of porous carbon composite nanofibers (CCNFs) with silicon-containing compounds and the introduction of a high specific surface area through the creation of pores by a simple thermal treatment. Blends of phenylsilane (PS) solutions at various concentrations and polyacrylonitrile (PAN) were electrospun into nanofibers. This process was followed by carbonization at 800 °C to create CCNFs with diameters of 60–200 nm and a high specific surface area of over 800 m2/g. The specific capacitance of the electrode in 6 M KOH solution was extraordinarily high (180 F/g). |
