Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a Mxene-based coating integrating conductivity, wave absorption and anticorrosion. Background technique [0002] MXene is an emerging two-dimensional sheet material with graphene-like structure. A variety of MXenes have been prepared. It is clear that MXenes have a sheet structure similar to graphene, and have good self-lubrication, toughness, and surface hydrophilicity. It can be used in many application fields such as catalysis, lubrication, adsorption, energy storage, anti-corrosion, and polymer composite material processing. The material has good electromagnetic shielding performance, mainly due to its good electromagnetic shielding performance. The interlayer electronic coupling and excellent conductivity (conductivity can be 4600S / cm) can effectively attenuate the electromagnetic waves entering the material. The electromagnetic shielding efficiency ...
