<p>Polypyrrole (PPy), a well-known conducting polymer, has attracted significant attention for supercapacitor applications due to its excellent pseudocapacitive behavior and high charge-storage capability. Covalent organic frameworks (COFs), on the other hand, are emerging porous crystalline materials characterized by high surface area, ordered nanoporous channels, extended π-conjugation, and abundant functional groups, making them highly promising for efficient ion diffusion and charge accommodation in energy storage systems. In this work, a triazine-based COF was integrated with PPy and simultaneously deposited onto a carbon cloth (CC) substrate via cyclic voltammetry electropolymerization to construct a hierarchical hybrid electrode. The successful formation of the CC/PPy/COF composite was confirmed through comprehensive structural and morphological characterization. Electrochemical results demonstrate a remarkable enhancement in performance, where the specific capacitance reaches 2250 mF /cm² at a current density of 3 mA/cm². This significant improvement is attributed to the synergistic interaction between PPy, COF, and the highly conductive and flexible carbon cloth substrate, which collectively facilitates rapid electron transport and efficient ion diffusion. In addition, the PPy network provides additional ion-accessible pathways, further improving charge storage behavior. The as-prepared electrode also exhibits excellent cycling stability, retaining 93.3% of its initial capacitance after 4000 charge–discharge cycles, indicating good structural integrity and long-term electrochemical durability. These results highlight the potential of the designed PPy/COF-based hybrid architecture for high-performance supercapacitor applications.</p>
