Facile synthesis of rGO/PANI/ZnO ternary nanocomposites for energy storage devices

Abstract

Due to the dire energy needs and the unavailability of energy storage devices, supercapacitors have become an inescapable substitute for energy storage systems. As a high energy density electrode material, we offer rGO/PANI/ZnO ternary nanocomposite designed via the polymerization method and are characterized by various analytical techniques. The results show that rGO/PANI/ZnO has the best capacitive behavior, with a specific capacity of 1546 F/g at 2 mV/s on the eggshell membrane electrode (ESME). The nanocomposite rGO/PANI/ZnO, on the other hand, presented the best cycling stability, retaining 97% of capacity after 3000 cycles. This is due to the fast transfer of electrons between rGO/ZnO and PANI in an electrochemical charge storage device. This research encompasses an enhanced flexible PANI-based electrode to become viable innovative wearable sensor alternative.
