Abstract: Supercapacitors have attracted considerable attention over the past decades because of their higher power density and longer cycle life than secondary batteries as well as their higher energy density compared with conventional electrical double-layer capacitors. Recently, graphene has emerged as a rapidly rising star in the field of material science. Due to the unique properties compared with other carbon materials, graphene becomes an attractive electrode material and also substrate material when compounded with polymers and inorganic particles for supercapacitors. In this study, a series of graphene based materials, including surfactant intercalated reduced graphene oxide, conjugated polyfluorene imidazolium ionic liquids intercalated reduced graphene oxide, graphene/polyaniline nanofiber composites, graphene/polypyrrole nanowire composites and nanostructured MnO2/graphene composites have been prepared, characterized and evaluated as supercapacitor electrodes. The systematic investigation of electrochemical properties of these materials in the thesis enables a better understanding of the graphene-based materials as electrodes for supercapacitors.
