摘要

This study incorporates a novel and cost-effective method for the in-situ fabrication of polyaniline (PANI) thin films through potentiostatic deposition under ambient conditions. PANI films were refined for supercapacitor applications by logically modifying the electrodeposition time. Comprehensive electrochemical characterization, including cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS), was conducted to evaluate their performance. The results suggest that the PANI-graphene oxide (GO) hybrid multilayer electrode displayed an impressive three-fold enhancement in the specific capacitance compared to the bare GO electrode. This work highlights the significant enhancement in the electrochemical performance achieved by incorporating a sandwich-like architecture between the active material and the substrate, offering promising potential for next-generation, high-performance energy storage devices.
