Abstract

Conductive polymers are promising materials due to their unique combination of electrical conductivity, lightweight nature, and mechanical flexibility. This research is focused on the synthesis of polyaniline (PANI)-carbon nanofiber (CNF) based conductive polymer and their ternary nanocomposites comprised with conductive metal oxides as dopants. The electrochemical performance of the synthesized nanocomposites was measured by an electrochemical workstation (three-electrode system). The result coming from cyclic voltammetry (CV) study revealed that the addition of CNF in the PANI backbones significantly increased electrochemical properties. Subsequently, it was found that PANI/CNF based ternary nanocomposite showed better specific capacitance than that of binary one (PANI/CNF). Moreover, among the metal oxide doped ternary composites, i.e., PANI/CNF/MnO₂ had the highest specific capacitance of 812.02 F/g and exhibited nearly 99.76% capacitive retention after 50 cycles. The area under the CV curve increases with the increasing scan rate. The synthesized ternary conductive polymer composites has superior charge storage capacity than that of bare and binary one. Longer charging times yielded better initial cycle results but led to poor cyclic properties, whereas shorter charging times provided good cyclic stability for the supercapacitor. Galvanostatic charging-discharging (GCD) of PANI/CNF/MnO₂ electrode based asymmetric hybrid supercapacitor at 1A constant current is more stable than symmetric supercapacitor in the discharging section.
