The current advances in energy storage devices has necessitated the development of functional polymer-based nanocomposites for supercapacitor applications. Supercapacitors are materials that exhibits enhanced capacitance, power density, life cycle, stability, durability, and catalytic activity. Hence, the incorporation of electrochemically active materials, particularly, carbon-based derivatives can significantly enhances synergistic properties with conducting polymers for advanced applications. Polymer-based derivates are receiving increasing attention and considerations based on their low cost, sustainability, and ease of production in supercapacitor development. Thus, this review highlights the details of the potentials and applications of polymer based nanocomposites from polyaniline (PANI), polypyrrole (PPy), and poly (3,4-ethylenedioxythiophene) (PEDOT) as an advanced materials for supercapacitor.
