Graphene/polypyrrole intercalating nanocomposites as supercapacitors electrode

Hierarchical graphene/polypyrrole nanocomposites were prepared via in-situ polymerization of self-assembled pyrrole. The composites achieved outstanding conductivity ∼1980 S cm−1 and demonstrated promising potential in supercapacitor, with a mass-specific capacitance hitting 650 F g−1 at 0.45 A g−1 current density.
