Microstructures and electromagnetic interference shielding properties of 2D defective Mo_1.33C (MXene)

MXene has shown great potential in electromagnetic interference (EMI) shielding field benefit due to its excellent conductivity and surface hydrophilicity. Vacancy-doped MXene can be obtained by selectively etching Al and Y of the 3D (Mo2/3Y1/3)(2)AlC precursor. Introducing defects such as vacancy into MXene can reduce its weight per unit volume and realize lightweight. Herein, for the first time, the defect-containing Mo1.33C MXene "paper" of 3.5 mu m thickness was tested as electromagnetic interference materials, showing promising results compared to other MXene and graphene-based materials.
