Abstract:Flaky polyaniline-reduced graphene oxide (PANI-rGO) composites have larger specific capacitance due to the improved redox charge of PANI in the composites, fabricated by simultaneous reduction of PANI-GO. The structural and morphological analyses were carried out using scanning electron microscopy, UV-Vis spectroscopy, and thermogravimetry. The results showed that the composites are flaky in shape. PANI is uniformly coated on GO, and PANI-rGO has specific capacitance as high as 1069 F·g-1 (1.71 F·cm-2) at a current density of 20 A·g-1, 5 times higher than PANI-GO; this is caused by the large surface and conductivity of the rGO in the composite.
Keywords:Polyaniline-reduced graphene oxide  Polyaniline-graphene oxide  Specific capacitance  Operating voltage
