Abstract：

Polypyrrole/MnO2　composites　with　unique　three-dimensional　network　structure　were　successfully　deposited　on　graphite　felt　(GF)　fibers　at　the　temperature　of　50　degrees　C　to　fabricate　PYMG-HT　composite,　which　can　be　used　as　a　free-standing　electrode　for　supercapacitors.　For　comparison,　PYMG-LT　electrode　was　also　prepared　in　ice　bath,　and　the　polypyrrole/MnO2　deposits　on　GF　prepared　at　0　degrees　C　exhibit　nanoflower　shape,　which　is　different　from　PYMG-HT.　The　PYMG-HT　electrode　displays　specific　capacitance　as　high　as　821.3　F　g(-1)　at　the　current　density　of　0.5　A　g(-1),　which　is　much　higher　than　that　of　PPy/MnO2　reported　previously.　Moreover,　the　PYMG-HT　exhibits　enhanced　capacitive　performance　compared　to　PYMG-LT　electrode.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
