Abstract

The homogeneous polyaniline–graphene oxide PANIGO nanocomposites were facilely assembled with a redox system in which cumene hydroperoxide CHP and iron dichloride FeCl2 acted as oxidant and reductant respectively Scanning electron microscopy SEM and transmission electron microscopy TEM images showed that PANI scales coated uniformly on the surface of GO sheets owing to the synergistic effect between the PANI and GO The obtained PANIGO nanocomposites exhibited improved electrochemical performance as an electrode material for supercapacitors compared with the pure PANI The specific capacitance of the PANIGO nanocomposites was high up to 3083 F g−1 much higher than that of the pure PANI with specific capacitance of 150 F g−1 at a current density of 1 A g−1 in 2 M H2SO4 electrolyte The Raman and XPS results illustrated that enhanced electrochemical performance might be attributed to the ππ conjugation between the PANI and GO sheets
