Dahlia-liked Carbon Nanohorns Decorated Graphene/Polyaniline Nanocomposite and Its Derived Nitrogen-doped Carbon for High-performance Supercapacitor

摘要

A dahlia-liked carbon nanohorns (CNHs) decorated graphene/ polyaniline (CGP) nanocomposite was prepared via in situ chemical oxidation and hydrazine hydrate reducing. Firstly, dahlia-liked CNHs decorated graphene oxide/polyaniline (CGOP) composite was synthesized from the polymerization of aniline monomers on the surface of graphene oxide with spherical dahlia-liked carbon nanohorns as spacers. Then, the CGP composite was obtained by reducing CGOP using hydrazine hydrate. CGP exhibited a uniform three-dimensional nanostructure because long cone-shaped tips of dahlia-liked CNHs spacers can boost the isolation effect of the nano- composite.
