2D MXenes for Electromagnetic Shielding: A Review

Abstract Since the first report on electromagnetic interference (EMI) shielding of 2D Ti 3 C 2 T x in 2016, MXenes have captured the leadership position among lightweight shielding materials due to many advantages, including their excellent shielding performance, outstanding metallic conductivity, low density, large specific surface area, tunable surface chemistry, and solution processability. MXenes triggered a huge interest in the materials research community, leading to over 100 reported publications on MXenes' EMI shielding within 3 years. Many MXenes composites and hybrids in different structural forms, such as compact and laminate structures, layer‐by‐layer assemblies, porous foams and aerogels, and segregated structures, have been explored to further improve the intrinsic EMI shielding properties of MXenes. This article comprehensively reviews the recent advancements in MXene‐based EMI shielding materials with different structural morphologies and provides an insight into future challenges and guidelines for finding material solutions for the next‐generation shielding applications.
