    Fabrication of polyaniline/mesoporous carbon/MnO 2 ternary nanocomposites and their enhanced electrochemical performance for supercapacitors

  • Original language description

    Polyaniline/mesoporous carbon/MnO 2 (PANI/CMK-3/MnO 2) ternary nanocomposites with a PANI nanolayer uniformly deposited on the CMK-3/MnO 2 particles were synthesized by chemical oxidative polymerization. Structure and morphology of the ternary compositeswere further characterized by TEM, XRD, FTIR and FE-SEM techniques. Electrochemical measurements demonstrated that the ternary composite with 12% MnO 2 content possessed enhanced specific capacitance of 695 Fg -1 and the capacitance retention was 88% after 1000 galvanostatic charge-discharge cycles at a current density of 1.0 Ag -1. The incorporation of MnO 2 nanoparticles can not only contribute to high capacitance but also stabilize the interaction between the quinoid ring of PANI and the CMK-3/MnO 2particles. The PANI nanolayer in the ternary composite restrains the dissolution of MnO 2 nanoparticles in acidic electrolyte so as to enhance their electrochemical utilization. The synergistic effect among three components may result in
