In this study, poly(vinyl alcohol) (PVA)/pectin/polypyrrole (PPy) and PVA/pectin/polydopamine (PDA)/PPy hydrogel films were prepared for use as supercapacitor electrodes. The synergistic effect of PDA and PPy on the electrochemical performance of the PVA/pectin/PDA/PPy hydrogel electrode was studied. PVA/pectin composite films (VE10, VE91, VE73, and VE55) with varying pectin proportions were prepared by cross-linking PVA with glutaraldehyde to serve as flexible and stretchable gel substrates for supercapacitor electrodes. PPy was synthesized on the surface of PVA/pectin films via chemical bath deposition. The incorporation of optimized pectin significantly enhanced the PPy content and the capacitance of the PVA/pectin/PPy film (VE73/PPy-90), achieving a measured value of 463.1 mF/cm
