In situ synthesis of cobalt doped polyaniline modified graphene composites fo…

Abstract. A new supercapacitor electrode material was prepared by the in situ oxidative polymerizat ion of aniline in presence of graphene and transition metal. The structural property of the composites has been determined by Raman spectroscopy. The formation of the comp osites has been confirmed by field emission scanning electron microscopy and the high resolution transmission electron mi…
