Review on polymer/MXene composites for electromagnetic interference shielding applications

         The Paper of the day covers the development of polymer/MXene composites for electromagnetic interference (EMI) shielding applications, addressing the growing demand for effective EMI shielding due to the rise of electronic devices and wireless technology. MXenes, a family of 2D transition metal carbides, exhibit high electrical conductivity and large surface areas, making them ideal for EMI shielding. The document explores various MXene preparation methods, including HF etching, in-situ etching, and molten salt etching, each with unique advantages and challenges. It also highlights structural designs of MXene composites (like "brick-mortar" and multilayer configurations) and their effectiveness in attenuating electromagnetic waves through mechanisms like absorption and reflection. The review concludes with future directions, emphasizing the need for improved processing methods to enhance scalability and environmental sustainability in developing next-generation EMI shielding materials.
