文摘

Hierarchically synthesized PEDOT encapsulated graphene-MnO2 nanocomposite. Microsphere fragmentation leads to good surface exposure of MnO2 on graphene matrix. XPS studies indicate presence of different oxidation states of Mn in composites. Maximum specific capacitance (213 F/g) found in ternary composite – PEDOT:Grp-MnO2.
