▎ 摘　　要

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.
