Recent Advances in the Electromagnetic Interference Shielding of 2D Materials beyond Graphene

Two-dimensional (2D) layered materials assume a central role in efforts to address the challenges associated with electromagnetic interference (EMI) due to undesirable effects of continuous exposure to electromagnetic fields. Recent progress on EMI shielding effectiveness (EMI SE) of 2D layered materials is highlighted, such as black phosphorus, hexagonal boron nitride, layered double hydroxides, and transition metal dichalcogenides, with a focus on the significant volume of work done with MXenes. The 2D structures yield large surface area and low density, and their unique electrical properties confer them a high potential for developing superior EMI shielding materials. Commercial products of EMI shielding materials are analyzed, and we discuss how these 2D materials could reach the market.
