Design and synthesis of nanostructured graphene-SnO2-polyaniline ternary composite and their excellent supercapacitor performance

Novel graphene-SnO2-polyaniline ternary composite is facilely synthesized by one-pot method. The test results show that the as-prepared ternary composite has a high specific capacitance (913.4 F g−1 at 5 mV s−1) and long cycle life (over 1000 times).
