Innovative Application of Functionalized Polyaniline-Based Nanocomposite Electrode Material for Supercapacitor (A Review)

Abstract

Energy supply is a crucial topic that is currently being discussed in many countries for an assortment of applications, encompassing medical, transportation, and communication. Consequently, many chemists are eager to propose superior materials and components for the fabrication of devices with positive electrochemical performances. It is important to remember that the efficacy of electrochemistry determines the material utilized in energy supply devices like supercapacitors. Many chemists are motivated by this to develop appropriate materials and composites for energy gadgets. Composites of nanocarbon conducting polyaniline show promise as electrode ingredients for these kinds of energy storage classifications. Composite hybrids are predicted to have a noteworthy impression on the clean and efficient energy systems of the future because of their stability in a foreseeable environment, inexpensive, and high electroactivity, and pseudo-capacitance polymers. An outline of recent studies and significant developments regarding the fabrication of conducting polyaniline-based hybridized nanocomposite electrodes for supercapacitors is presented in this article. The electrochemistry of functionalized polyaniline polymer nano-composites is discussed in this manuscript due to its wide-ranging effects on energy production through strong redox reactions. Here, we have focused on developing polyaniline-based nanocomposite architectures that have been altered to advance them technologically through allied pendant sulfonic acid groups, carbonaceous materials, and transition metal oxide groups. These materials are very effective in today’s energy supply devices because of their ion exchange, low reaction energy, and simple electrochemical reactions. Discussions are held regarding the difficulties and viewpoints associated with the logical design and production of polyaniline hybridized nanocomposites for energy storage. This could be a future innovation that helps administrators maintain control and a balanced approach to further meet practical needs.
