ABSTRACT:
A high surface area carbon nanofiber is provided. The carbon nanofiber has an outer surface on which a porous high surface area layer is formed. A method of making the high surface area carbon nanofiber includes pyrolizing a polymeric coating substance provided on the outer surface of the carbon nanofiber at a temperature below the temperature at which the polymeric coating substance melts. The polymeric coating substance used as the high surface area around the carbon nanofiber may include phenolics-formaldehyde, polyacrylonitrile, styrene, divinyl benzene, cellulosic polymers and cyclotrimerized diethynyl benzene. The high surface area polymer which covers the carbon nanofiber may be functionalized with one or more functional groups.
