  • Method of preparing doped and/or composite carbon fibers
    Patent number: 10422054
    Abstract: 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° C.
    Type: Grant
    Filed: September 22, 2016
    Date of Patent: September 24, 2019
    Assignee: Board of Regents of the University of Texas System
    Inventors: Karen Lozano, Lee Daniel Cremar, Maria del Rocio Nava Lara, Mandana Akia
