摘要: Polyaniline/mesoporous carbon/MnO2 (PANI/CMK-3/MnO2) ternary nanocomposites with a PANI nanolayer uniformly deposited on the CMK-3/MnO2 particles were synthesized by chemical oxidative polymerization. Structure and morphology of composites further characterized TEM, XRD, FTIR FE-SEM techniques. Electrochemical measurements demonstrated that composite 12% MnO2 content possessed enhanced specific capacitance 695 F g−1 retention was 88% after 1000 galvanostatic charge-discharge cycles at current density 1.0 A g−1. The incorporation nanoparticles can not only contribute to high but also stabilize interaction between quinoid ring particles. in restrains dissolution acidic electrolyte so as enhance their electrochemical utilization. synergistic effect among three components may result cycling stability composites.
