摘要

This study reports the fabrication and structural characterization of novel ternary hierarchical carbon nanofibers (CNFs) surface-grafted with carbon nanotubes (CNTs) and then coated with conductive polymer. During the process, CNFs were produced by carbonization of as-electrospun polyacrylonitrilenanofibers with the diameter of ~200-400 nm, followed by CNT-growth via chemical vapor deposition (CVD). Ultrathin PANI film was further deposited onto the porous CNT-grafted CNFs via in-situ polymerization of anilines in aqueous solution. Such nanostructures can be used as electrodes for use in supercapacitors, in which the PANI films supported by conductive CNT/CNF scaffolds can trigger favorable pseudocapacitive effect and meanwhile the carbon substrate keeps low electrical resistance during cycling. These unique hierarchal nanostructures are excellent candidates for use as electrodes in high-performance supercapacitors for energy storage and management.
