| Summary: | This study demonstrates the dispersion of MnO2 nanoparticles in Polyindole (PIn) to optimize the supercapacitive properties of MnO2-PIn composites. As expected, the supercapacitive properties of MnO2-PIn composites influenced by the addition of MnO2 nanoparticles and it is optimized for 1 wt.% of MnO2 concentration. The 1 Wt.% MnO2 loaded PIn composite shows specific capacitance of the order 1558 Fg−1 at a scan rate of 50 mVs−1. The main accomplishment of present work is that the 1 Wt.% MnO2 loaded PIn composite shows long-term stability that is capacitance retention up to 6000 cycles. Galvanostatic charge/discharge curves of 1 Wt.% MnO2 loaded PIn composite shows long nearly symmetric behavior which is suitable for range of practical applications. |
