Abstract A series of composites of polypyrrole and graphene oxide (GO) were synthesized by in-situ-polymerization with different ratios of water to alcohol in the solvents for the blending of GO and Py monomer. The structures and morphologies of the resultant composite materials were characterized by infrared spectroscopy, SEM, and TEM, while electrochemical performances were tested by means of cyclic voltammetry (CV) and galvanostatic charge-discharge test. The results showed that all the composite materials have outstanding capacitive performances and good stabilities, and the composite synthesized under 9∶1 water-alcohol ratio (volume ratio) exhibits the most stable capacitive performance.
