Fabrication of porous carbon nanofibers with adjustable pore sizes as electro…

Abstract. We report a facile method for obtaining extremely high surface area and uniformly porous carbon nanofibers for supercapacitors. Blends of polyacrylonitrile and sacrificial Nafion at different compositions have been electrospun into non-woven nanofiber mats with diameters in the range of 200-400 nm. Electrospun nanofiber mats are then subjected to carbonization to obtain porous car…
