中文摘要	Graphene/manganese dioxide (MnO2) composite papers (GMCP) are fabricated via a simple three-step routepreparation of graphene oxide/MnO2 composite (GOMC) dispersion, subsequent vacuum ﬁltration of GOMC dispersion to achieve graphene oxide/MnO2 composite paper (GOMCP), and ﬁnally thermal reduction of GOMCP to generate GMCP. The morphology and microstructure of the prepared samples are characterized by ﬁeld-emission scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, Fourier transformation infrared spectroscopy, thermal gravimetric analysis and X-ray photoelectron spectroscopy. Moreover, as a binder-free and ﬂexible electrode material for supercapacitors, the electrochemical properties of the prepared GMCP are evaluated by cyclic voltammetry and galvanostatic charge/discharge tests. As a result, the speciﬁc capacitance of the GMCP with the MnO2 weight ratio of 24% (GMCP-24) reaches 256 F g 1 at a current density of 500 mA g 1 and also shows good cycle stability, indicating a promising potential application as an effective electrode material for supercapacitors.
