NOVELTY - Preparing conductive, wave-absorbing and anti-corrosion integrated coating based on two-dimentional carbides and nitrides (MXene) comprises e.g. (1) functionalizing surface of the magnetic filler with amino group, and obtain a magnetic material with amino groups on the surface, dispersing 1-10 pts. wt. graphene in 1-100 pts. wt. water, adding 1-5 pts. wt. non-ionic surfactant, adjusting pH to 9-11, then adding 1-100 pts. wt. magnetic material with amino groups on the surface, stirring at high speed for 10-30 minutes, then emulsifying with an emulsification pump for 30-60 minutes, and drying to obtain a mixture of graphene nanosheets-magnetic filler, and (2) adding 1-10 pts. wt. graphene, 1-10 pts. wt. Mxene, 1-100 pts. wt. magnetic filler with amino groups on surface to 1-100 pts. wt. water, adjusting pH to 9-11, then stirring at high speed for 1-60 minutes, performing emulsification treatment for 30-120 minutes with an emulsification pump. USE - The method is useful for preparing conductive, wave-absorbing and anti-corrosion integrated coating based on two-dimentional carbides and nitrides (MXene). ADVANTAGE - The coating: has good conductivity, wave-absorbing performance and anti-corrosion performance.
