Review on polymer/MXene composites for electromagnetic interference shielding applications

With the increasing popularity of electronic devices and wireless technology, the issue of electromagnetic interference (EMI) has attracted widespread attention all over the world. In response to this challenge, it is of great significance to develop novel EMI shielding composites with high absorption performance. In recent years, 2D MXene series nanomaterials have gained prominence in the field of EMI shielding due to their remarkable electrical conductivity, mechanical strength, and chemically active surfaces. Herein, we review recent progress on polymer/MXene EMI composites. Firstly, the preparation method of MXene nanosheets and the mechanism and experimental calculation of EMI shielding are introduced, and then the main structural design ideas and corresponding preparation methods of polymer/MXene EMI shielding composite materials are objectively summarized, and their advantages and disadvantages in electromagnetic shielding applications are analyzed. Finally, this review highlights the current challenges faced by polymer/MXene composites in EMI shielding applications and puts forth innovative concepts for the development of next-generation high-performance EMI shielding materials.
