Architecting MXene-based nanocomposite coatings: A paradigm shift in electromagnetic shielding

Abstract

MXenes, a swiftly sprouting genus of transition metals with two-dimensional (2D) structures have engrossed momentous exploration interest due to their peculiar chemicophysical attributes and disparate prospective solicitations. This review bestows an encyclopaedic investigation of the characteristics of MXenes, such as their exceptional electromagnetic shielding, configurable chemistry, and stratified structure. These possessions are predominantly determined by idiosyncratic configuration, with–OH, –O, and –F as functional groups. The nucleuses on pioneering synthesis and etching for several MXenes. The emphasis on the exceptional electromagnetic interference (EMI) shielding capabilities of MXenes, which is conceivably pronounced by inherent outstanding dielectric characteristics, and multi-scale structures that postulate efficacious raptness and replication of electromagnetic waves. Furthermore, the photothermal conversion characteristics of MXenes are philanthroping. This mightily interests contenders for various applications. MXenes, illustrated elevated mechanical properties, which are levied in relation to their assimilation into composite materials, where they serve as fortifying agents to enhance robustness and longevity. Moreover, the review scrutinizes the diverse uses for MXenes, including highly vital aerospace, stealth, military, wearable electronics, and energy repository devices like supercapacitors. By synthesizing current progress in the investigation of MXenes, this paper emphasizes their capacity to operate as versatile materials in futuristic defence pertinent technologies.
