Emerging Advancements in Polypyrrole MXene Hybrid Nanoarchitectonics for Capacitive Energy Storage Applications

Abstract: Recent advancement in nanotechnology has brought about the discovery of various nanomaterials such as graphene (GN), montmorillonites (MMT), carbon nanotubes (CNT), and very recently, MXene (MX). MX has attracted considerable attention as a 2-dimensional (2-D) material because of its inherent superior properties such as large surface area, high aspect ratio, electrical, thermal, and mechanical disposition thereby enlarging its application as a multifunctional material. On the other hand, Polypyrrole (PPy) belongs to the genre of conducting polymers (CPs) which have attracted increasing attention due to its possession of good biocompatibility, inherently high conductivity, and ease of synthesis. In comparison with conductive polymers, PPy is commercially more viable and this has increased its extent of application as a material for medicals, secondary batteries, electrochemical sensors, amongst others. Generally, nanotechnological embedment of nanoparticles in polymeric matrices has resulted in the formation of polymeric nanocomposites with enhanced properties in comparison with the precursor materials. Hence, in order to achieve an enhanced usage in energy storage and enlarge the scope of application of these materials, various approaches are utilized in hybridizing conducting MXene with PPy in order to obtain a hybrid multifunctional material with enhanced electrochemical properties. Therefore, this paper elucidate the recent advancements in the preparation approaches of MXene/polypyrrole hybrid nanoarchitectonics for energy storage applications.
