ABSTRACT
Polymer nanocomposites have received significant research interest due to the advantage of tailoring their properties with respect to required applications. The selection of a nanofiller as an additive into the polymer plays a crucial role in the development of high-throughput nanocomposites. The efficiency of polymer nanocomposites is enhanced to a greater extent on using two-dimensional (2D) materials as nanofillers. One of the advanced 2D materials of MXenes (transition metal carbide) reported in recent times and recognized as an efficient nanomaterial in different applications due to its excellent properties, such as ease of dispersibility, pore structure, flexibility, remarkable surface chemistry, restrained optical, mechanical, and metallic conductivity. In light of these properties, MXenes are also employed as a nanofiller to obtain nanocomposites. MXene/polymer nanocomposites have shown superior properties, such as excellent electromagnetic interference shielding, high volumetric charge storage, catalytic activity, and mechanical stability, compared to other nanocomposites. Among the mentioned, in this report, the high charge storage capacity of MXene/polymer nanocomposite electrode materials in energy conversion and storage is critically reviewed.
