dc.description.abstract A facile two-step strategy is adopted to construct a free-standing composite paper of MnO<inf>2</inf> nanoflake/polyaniline (PANI) nanorod hybrid nanostructures on reduced graphene oxide (RGO) for flexible supercapacitor electrode application. MnO<inf>2</inf> nanoflakes are first grown on RGO paper via an electrodeposition method, followed by assembly of PANI nanorods between MnO<inf>2</inf> nanoflakes by in situ polymerization using camphorsulfonic acid as a dopant. The morphology and structure of the composite paper are characterized and the electrochemical properties are systematically investigated. The interconnected PANI nanorods deposited on the interlaced MnO<inf>2</inf> nanoflakes have a length of ∼100 nm and a diameter of ∼30 nm, creating plenty of open porous structures which are beneficial for ion penetration into the electrode. The RGO/MnO<inf>2</inf>/PANI composite paper shows a large specific capacitance of 636.5 F g-1 at 1.0 A g-1 in 1.0 M Na<inf>2</inf>SO<inf>4</inf> electrolyte and excellent cycling stability (85% capacitance retention after 104 cycles). The optimized composite structure with more electroactive sites, fast ion and electron transfer, and strong structural integrity endows the ternary composite paper electrode with outstanding electrochemical performance. © The Royal Society of Chemistry 2015. en
