Prospects of Hybrid Conjugated Polymers Loaded Graphene in Electrochemical Energy Storage Applications

The synergy between graphene and conducting polymers has the potential to revolutionize the energy storage sector to a more dependable, sustainable, and affordable energy source. Introducing graphene nanoparticles in the conductive polymers (polypyrrole and polythiophene) nanoparticles is a prospective technique to increase the charge transfer efficiency of the resulting nanocomposite. Subsequently, the fabrication method of graphene-polymer nanoelectrode is the most critical factor responsible for their excellent performance. This review presents a concise summary of graphene (Gr), polypyrrole (PPy), and polythiophene (PTh) synthesis techniques. The study revealed that the dispersion of nanoparticles could be controlled by suitable solvent, mixing approach, and drying conditions. In addition, the PPy/PTh/Gr nanocomposite is envisaged to be a promising nanoelectrode for sustainable and efficient energy storage capabilities. The future approaches to developing improved materials synthesis techniques for multi-applications (supercapacitors, sensors, and photovoltaic) are also provided.
