Ionic Conductivity and Structural Studies of Poly(Methyl Methacrylate)-Grafted Natural Rubber-Graphene Oxide Integrated with Ammonium Triflate Based Polymer Electrolytes

Article Preview

Abstract:

The performance of polymer electrolyte can be improved through various approaches, including the addition of filler and dopant salt, in which has demonstrated significant potential for enhancing performance in electrochemical applications. The purpose of this study was to investigate the ionic conductivity and structural studies of 49% poly (methyl methacrylate) grafted natural rubber (MG49)-graphene oxide (GO) integrated with ammonium triflate (NH4CF3SO3) based polymer electrolytes. The highest ionic conductivity, 4.42 x 10-6 Scm-1, was achieved with 25 wt.% of NH4CF3SO3. ATR-FTIR analysis showed a reduction in C=O peak intensity, indicating interaction between the polymer matrix and salt, while optical microscopy (OM) revealed that the 25 wt.% sample had the smoothest surface and the most amorphous structure, correlating with the highest ionic conductivity. These results suggest that nanocomposite polymer electrolytes based on MG30-GO-NH4CF3SO3 have potential for energy storage applications.
