MXene-Based Composites for Electromagnetic Shielding

Abstract

With the miniaturization and high-frequency development of electronic devices, electromagnetic interference (EMI) has become a critical technical bottleneck and research hotspot. There is an urgent demand for the exploration of lightweight, high-efficiency, and multifunctional shielding materials. Traditional metallic materials suffer from inherent limitations such as high density and poor environmental stability. In this context, developing advanced alternatives with superior shielding effectiveness and broader functional integration has attracted increasing attention. MXene is a novel two-dimensional transition metal carbide/nitride and exhibits great potential in the field of electromagnetic interference shielding because of its excellent electrical conductivity, hydrophilicity, and tunable surface chemistry. This paper reviews the research progress of MXene-based composites. It focuses on performance improvement strategies including composite modification, structural design, and surface modification, as well as their multifunctional applications in flexible electronics, thermal management, environmental adaptability, and integrated energy storage-shielding. Finally, it points out current challenges and future development trends from laboratory research to industrial application.
