PolyanilinePolyaniline, amongst many conducting polymersConducting polymer, has shown great promise as an energy storageEnergy storage material due to low cost, ease of synthesis, light weight, and electronic conductivityConductivity. 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 polyanilinePolyaniline-reduced graphene oxideReduced graphene oxide nanocomposite. The synthesis of the nanocomposites was done via chemical oxidation polymerization and the dopants were introduced during the polymerization process. PANI/rGO-Ptsa delivered the highest specific capacitance of 653 Fg−1 at a specific current of 0.5 Ag−1, which is over two times greater than the specific capacitance of pristine PANI. The electrochemical and morphological properties of PANI/rGO-Ptsa reveal that the introduction of the organic dopant was responsible for the increase in conductivityConductivity and allowed for fast diffusionDiffusion of electrolyte ions.
