MXene-Based Electromagnetic Interference Shielding Materials: A Leap From Fundamental Research to Intelligent Customization.

The development of new electromagnetic interference (EMI) shielding materials with excellent overall performance has become a top priority, yet currently available EMI shielding materials are limited in terms of customization and application flexibility. A successful example is MXene-based EMI shielding materials, which exhibit outstanding electrical conductivity, tunable surface chemistry, and excellent solution processing, offering opportunities for intelligent customization in the field of EMI shielding. This review summarizes key developments from 2016 to 2024, highlighting MXene-based composites achieving EMI shielding effectiveness (SE) over 80 dB, ultralow densities below 0.1 g cm, and SSE/t values exceeding 30 000 dB·cm g. Herein, the latest advances in MXene-based EMI shielding materials, including fundamental experiments and intelligent customization, are outlined. Furthermore, recent progress in AI-assisted material design platforms, GHz-THz broadband shielding for 6G applications, and multifunctional integrated systems are highlighted. These efforts aim to provide efficient, lightweight, and flexible EMI shielding for next-generation electronic devices. Finally, based on the current research landscape, this article looks into the future development directions and application prospects of MXene-based EMI shielding materials, providing strategic insights for integration in advanced electronic systems.
