In the development of flexible smart electronics, fabricating electrodes with optimized architectures to achieve superior electrochemical performance remains a significant challenge. This study presents two-step synthesis and characterization polypyrrole (PPy)-MnO2/carbon cloth (CC) nanocomposite. The MnO2/CC substrate was first prepared via hydrothermal method, followed by uniform PPy coating through vapor-phase polymerization in presence an oxidizing agent. Electrochemical measurements revealed substantial enhancement performance, specific capacitance increasing from 123.1 mF/cm2 for composite 324.5 PPy/MnO2/CC at current density 2.5 mA/cm2. remarkable improvement can be attributed synergistic effects between conductive polymer formation additional ion transport channels facilitated coating. work provides valuable insights designing high-performance electrode materials advances composite-based energy storage devices.
