Polyaniline is covalently functionalized onto the RGO surface in the presence of carbon nanotubes and used for high performance supercapacitors.
A facile two-step strategy is adopted to construct a free-standing composite paper of MnO2 nanoflake/polyaniline (PANI) nanorod hybrid nanostructures on reduced graphene oxide (RGO) for flexible supercapacitor electrode application.
