Supercapacitors possess significant advantages compared to other energy storages due to its fast charging and discharging, long cycle life, low cost and good environmental friendliness. In this work, a layer-by-layer (LBL) of polypyrrole/graphene oxide and polypyrrole/manganese oxide (PPy/GO|PPy/MnO2) was prepared via a facile electrochemical deposition. The field emission scanning electron microscopy (FESEM) image clearly showed that PPy/MnO2 was uniformly deposited on PPy/GO. The PPy/GO|PPy/MnO2 LBL composite displayed a high specific capacitance of 786.6 Fg-1 compared to its individual single layers with superior specific energy of 52.3 Wh kg-1, specific power of 1392.9 W kg-1 and good cycling stability over 1000 cycles. The remarkable supercapacitive performance was contributed by the synergistic effect between each material proving an outstanding candidate electrode material for supercapacitor.
