Recent progress on MXene‐based aerogels for electromagnetic interference shielding

Abstract The rapid advancement of electronic devices and wireless communication has heightened the demand for electromagnetic interference (EMI) shielding materials to ensure electromagnetic compatibility. Transition metal carbides/nitrides (MXenes) have emerged as promising candidates due to their outstanding electrical conductivity, large specific surface area, rich surface functionalities, and exceptional mechanical properties. These attributes make MXenes particularly advantageous when assembled into lightweight, three‐dimensional (3D) porous aerogels that deliver exceptional EMI shielding performance. This review systematically discusses the fundamental mechanisms of EMI shielding, emphasizing critical influencing factors and key evaluation parameters. Recent advances in MXene‐based aerogels for EMI shielding are summarized, highlighting effective component and structural design strategies. Additionally, the review explores the synergistic relationships between compositional adjustments and structural modulation in MXene‐based aerogels, systematically evaluating their impact on EMI shielding performance. Finally, current challenges and future development prospects of MXene‐based aerogels for EMI shielding applications are critically addressed, proposing research directions towards next‐generation lightweight and high‐performance shielding materials.
