中文摘要	Flexible graphene sheet (GS)/polyaniline (PANi) nanoﬁbers composite paper was prepared via a facile and fast two-step route composed of electrostatic adsorption between negatively-charged poly(sodium 4-styrenesulfonate) (PSS) mediated GS (coded as PSS-GS) and positively-charged PANi nanoﬁbers and the follow-up vacuum ﬁltration of the as-prepared PSS-GS/PANi nanoﬁbers suspension. By observations of ﬁeld emission scanning electron microscopy (FE-SEM) and high resolution transmission electron microscopy (HR-TEM), it is clearly seen that representative and highly ordered layered PSS-GS/PANi composite papers have been achieved and PANi nanoﬁbers are coated by PSS-GS. In addition, the synthesized PSS-GS/PANi composite papers are also characterized by Raman spectroscopy and Fourier transform infrared (FTIR) spectroscopy, and the results further conﬁrm the successful synthesis of PSS-GS/PANi composites and the existence of strong interaction between PSS-GS and PANi nanoﬁbers. The most interesting thing is the eﬀective synergy can remarkably improve electrochemical properties of GS by introducing PANi nanoﬁbers, which can ascribe to high surface area of GS and good combination between PSS-GS and PANi nanoﬁbers. The highest speciﬁc capacitance of the composites reaches 301 F/g. Thermogravimetry analysis (TGA) indicates that the thermal stability of the PSS-GS/PANi composites is obviously improved compared to the pure PSS-GS and PANi.
