Microstructures and electromagnetic interference shielding properties of 2D defective Mo1.33C (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 (Mo[Formula: see text]Y[Formula: see text]) 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 Mo[Formula: see text]C MXene “paper” of 3.5 [Formula: see text]m thickness was tested as electromagnetic interference materials, showing promising results compared to other MXene and graphene-based materials.
