MnO2/polyaniline hybrid nanostructures on carbon cloth for supercapacitor electrodes

Original language description

A facile two-step strategy is developed for synthesis of MnO2/polyaniline (PANI) hybrid nanostructures on carbon cloth (CC). Vertically aligned PANI nanofiber arrays were firstly grown on CC via chemical oxidative polymerization, and MnO2 nanoparticles were then deposited on the surface of PANI nanofibers via redox reaction between PANI and KMnO4 solution. Structural and morphological characterizations of composites were investigated by FESEM, Raman, and XPS techniques, respectively. Electrochemical performance of the composites as supercapacitor electrode materials was evaluated by cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy techniques. The results demonstrate that the morphology and areal specific capacitance of the MnO2/PANI/CC composite vary with MnO2 deposition time. The ternary composite with 6 h MnO2 deposition exhibits a high areal capacitance of 1.56 F cmMINUS SIGN 2 at the scan rate of 10 mV sMINUS SIGN 1 and 0.99 F cmMINUS SIGN 2 at a current density of 2 mA cmMINUS SIGN 2 and still maintains 88.1 % of the original capacitance after 1000 charge-discharge cycles at a large current density of 10 mA cmMINUS SIGN 2.The excellent performance is due to the synergistic effect from the combination of two active pseudo materials and 3D conductive CC backbone. This study further highlights the importance of optimal design and control of material structures in supercapacitor applications.
