Polypyrrole/manganese　dioxide　nanocomposite　was　deposited　on　graphite　felt　(GF)　via　electrodeposition　to　fabricate　polypyrrole/manganese　dioxide/graphite　felt　(PYMG),　which　can　be　used　as　novel　free-standing　electrode　for　supercapacitors.　The　microstructure　and　morphology　of　the　as-prepared　samples　were　characterized　by　Fourier　transform　infrared　(FTIR)　spectra,　X-ray　diffraction　(XRD),　X-ray　photoelectron　spectroscopy　(XPS),　scanning　electron　microscopy　(SEM)　and　transmission　electron　microscopy　(TEM).　Cyclic　voltammogram　(CV),　chronopotentiometry　(CP)　and　electrochemical　impedance　spectroscopy　(EIS)　techniques　were　employed　to　investigate　the　electrochemical　performance　of　the　composites.　The　PYMG　electrode　displayed　specific　capacitance　as　high　as　596.3　Fg(-1)　at　the　current　density　of　0.5　Ag-1,　which　is　much　higher　than　that　of　polypyrrole/manganese　dioxide　(PPy/MnO2)　composite　reported　previously.　The　high　specific　capacitance　of　PYMG　may　be　attributed　to　the　fact　that　the　porous　GF　is　a　good　conductive　matrix　for　the　dispersion　of　PPy/MnO2　composite　and　it　can　facilitate　easy　access　of　electrolytes　to　the　electrode,　which　results　in　enhancement　of　the　electrochemical　performance　of　the　composite.　Furthermore,　the　PYMG　composite　exhibited　enhanced　specific　capacitance　compared　to　MnO2/GF　(MGF)　and　PPy/GF,　which　may　be　ascribed　to　the　synergistic　effect　of　PPy　and　MnO2.
