A method of producing doped carbon fibers, doped systems to prepare graphene-fiber hybrid structures, or doped carbon nanostructures, includes forming doped polymer precursors and decomposing at least a portion of the polymeric precursors to form carbon fibers. The decomposition may be accomplished by treating the doped polymer precursors with acid vapor from an aqueous acid solution at a temperature of less than 250&#xb0; C.

Method of preparing doped and/or composite carbon fibers

A method of producing carbon fiber, yarns, and nonwoven carbon fiber cloths, includes forming suitable polymeric precursor microfibers and/or nanofibers using a centrifugal spinning process and decomposing at least a portion of the polymeric precursor fibers to form carbon fibers. The decomposition may be accomplished by treating the polymeric precursor fibers with acid vapor from an aqueous acid solution at a temperature of less than 250&#xb0; C.
