英文摘要	In this study, reduced graphene oxide (GO)/polyaniline composites (GP) were successfully fabricated through a novel one-pot synthesis route with 4-methylaniline as a reductant for GO followed by in-situ polymerization of aniline. The results of X-ray diffraction and Raman spectroscopy revealed that GO was successfully reduced by 4-methylaniline. Meanwhile, the effect of aniline amount on the microstructure and electrochemical performance of the as-prepared GP was optimized by tuning the feed ratios of aniline to GO. The results demonstrated that the feed ratio of aniline to GO played a very significant role in constructing the nano-structure of GP, and furthermore determined their electrochemical performance. GP displayed a layer-like structure evenly covered by polyaniline (PANI) nanowires with the feed ratio of aniline to GO of 30/1 (m/m). Under this condition, the composite exhibited a maximum specific capacitance of 530.4 F g−1 at a current density of 0.5 A g−1, remarkably higher than that of unitary PANI (367.9 F g−1), and showed an excellent rate performance (411.1 F g−1 at 20 A g−1) as well. Moreover, the composite delivered good cycling stability with less than 8% decrease in the specific capacitance after 2000 cycles at a scan rate of 100 mV s−1, which was a great improvement over the unitary PANI (69.1%).
