A new graphene (GA)/nitrogen-doped ordered mesoporous carbon (NMC) nanosheet was synthesized in situ by a triblock-copolymer assembly directly on graphene oxide. The strong interaction of NMC and GA in the form of N-O bonding limits GA aggregation. The resulting composite GA/NMC-95% with the NMC mass content of 95% shows a high surface area (1569 m(2) g(-1)) and good electronic conductivity. As an electrode material for supercapacitor in 1 mol L-1 H2SO4 electrolyte, it delivers specific capacitance as high as 377 F g(-1) at 0.2 A g(-1), outstanding rate capability and excellent cycling stability.
