Abstract
Camouflage against the danger of electromagnetic radiation is becoming more important due to the rapid growth of wireless communication and electronic devices, which negatively impacts the regular functioning of electrical and electronic equipment. Electromagnetic shielding materials (SMs) that are bendable and ultra-lightweight are hence thought to be crucial for mitigating the detrimental impacts of electromagnetic waves. MXenes have gained a prominent spot among ultra-lightweight shielding materials since the first study on the electromagnetic interference (EMI) shielding of two-dimensional MXenes in 2016, because of a plethora of benefits, including their superior shielding properties, exceptional metallic conductivity from 5 S/cm to over 20,000 S/cm, low density of 2.39 g/cm(3), large specific surface area (SSA) of 18 m(2) g(-1), solution processability, and tunable surface chemistry. To further enhance the inherent EMI shielding (EMIS) capabilities of MXenes, numerous MXene nanocomposites in various structural configurations, including layer-by-layer assembly, laminate and compact frameworks, porous foams, aerogels, and partitioned edifices, have been investigated. This study includes the manufacturing procedure, advantages, disadvantages, and principles in depth, moving from the fundamentals of EMIS through the most recent research on MXene nanocomposites. Based on these breakthroughs, this review seeks to share some insightful information about the multifunctional uses of MXene nanocomposites and their advances as EMI SMs.
