| Abstract Scope |
Polyaniline, amongst many conducting polymers, has shown great promise as an energy storage material due to low cost, ease of synthesis, light weight, and electronic conductivity. However, in supercapacitor applications, PANI-based electrodes suffer structural deterioration and volumetric instability during repeated charging and discharging processes. In this study, we investigated the influence of organic dopants (p-Toluenesulfonic acid (PTSA) and Dodecylbenzenesulfonic acid (DBSA)) on the electrochemical performance of polyaniline-reduced graphene oxide nanocomposite. The synthesis of the nanocomposites was done via chemical oxidation polymerization and the dopants introduced during the polymerization process. PANI/RGO-PTSA delivered the highest specific capacitance of 653 Fg-1 at a specific current of 0.8 Ag-1 , which is over 2.5 times greater than the specific capacitance of pristine PANI. The electrochemical and morphological properties of PANI/RGO-PTSA reveals that the introduction of the organic dopant was responsible for the increase in conductivity and allowed for fast diffusion of electrolyte ions. |
