Graphene has the chemical structure consisting of two-dimensional layer of sp2-bonded carbon atoms, and have attracted considerable interest over the last ten years due to the extraordinary electrical, thermal, and mechanical properties arising from its unique structure. Polythiophene has been much interested due to its environmental stability, high electrical conductivity, and its applications. Graphene oxide was obtained using modified Hummer’s method and was reduced by sodium borohydride. We prepared nitrogen doped graphene with urea using high-pressure reactor and nanocomposite was obtained in the presence of graphene and thiophene monomer through chemical polymerization. We investigated the effect of graphene as filler on thermal and electrochemical properties of the composite. The surface morphology and structure of composites were characterized using XRD, SEM, TEM and XPS. Thermal and electrochemical properties of composites were studied using TGA and CV. |
