Peng Chen et al. prepared the hybrid of Sulfonated graphene with NMC by aqueous phase route involve the mixing of 3-hydroxyaniline, F-127, Hexamine, Mesitylene and ammonia at 80°C for 24 h followed by ultrasonication with sulfonated graphene (SG) about 6 h and the subsequent calcination at 800 °C for 3 h [772]. The hybrid of NMC with SG submitted the gravimetric capacitance of 304.2 F g -1 at 1 A g -1 in 1 M H2SO4 which is superior to OMC (128.9
