FNM-Based Polymeric Nanocomposites Functionalized for Supercapacitor Applications in Different Industries

The primary issues that all people currently face are the energy crisis and environmental pollution. Owing to their high cost and reduction of environmental friendliness, synthetic-based materials need to be substituted as biodegradable based materials. Polymer nanocomposite research promotes the scope of energy storage technologies for batteries, fuel cells, capacitors, and supercapacitors. Basically, electrochemical devices consist of two major divisions such as electrodes and electrolytes. To fulfil the rising demand for green energy, it is critical to develop environmentally friendly and ecologically sustainable electrode materials. Organic cathodes have several, significantly superior benefits compared to those of inorganic materials. The redox stability, diversity of structural elements, multielectron reactions, and quick reaction kinetics of organic electrode materials were the most encouraging factors. Especially, different types of polymers are used in supercapacitor applications as electrode materials, and/or electrolytes. The characteristics of the polymers are improved by the functionalization with other organic and/or inorganic species, such as inorganic salts, carbon derivatives, nanofillers, etc. The invention of the next generation of functional polymers will depend greatly on our capacity to control the structures, properties, and capabilities of polymer electrolytes. Using synthesis methods to generate the necessary chemical structures, morphologies, and thermal, mechanical, and electrochemical characteristics is a promising strategy. This chapter deals with the role of polymer nanocomposites for supercapacitor applications. Properties of different polymers and their nanocomposites will be discussed. The preparation techniques of polymers and polymer nanocomposites will be discussed. Applications of polymer nanocomposites-based supercapacitors in different industries will be elaborately discussed. The future and safety aspects of polymers-based supercapacitors will be addressed.
