Graphene has extraordinary electrical, thermal, and mechanical properties arising from its unique structure. Polyaniline(PANI) has unique properties such as facile synthesis and simple acid/base doping/dedoping. Graphene oxide was obtained using modified Hummer’s method and was reduced. Composite was prepared in the presence of graphene under acid conditions through direct electropolymerization. We investigated the effect of graphene as filler on thermal and electrochemical properties of the composite. The surface morphology and structure were characterized using XRD, SEM, TEM, and TGA. The Surface morphology of composites show randomly aggregated, crumbled graphene flakes and PANI covered on it. The results of TGA showed that the composite exhibits better thermal stability compared with the PANI. Capacitive and redox characteristics of composite were studied using CV. |
