MXene, a new two-dimensional material, is composed of several atomic layer thick transition metal carbides, nitrides or carbonitrides, which was originally present in 2011. Because of the hydroxyl groups or terminal oxygen on the surface of the MXene materials, the MXene materials have metal conductivity of transition metal carbide, and are increasingly widely applied to supercapacitors, batteries, electromagnetic interference shielding, composite materials and the like. Different from the surface of two-dimensional materials such as graphene and transition dihalide carbon, the functional groups of the two-dimensional materials can be chemically modified, and the surface of the two-dimensional materials can be provided with active groups through functional design, so that the adhesive force between powder and metal can be improved conveniently; meanwhile, compared with graphene, the graphene has no hydrogen bond between layers, so that the graphene has good interlayer sliding performance, and the abrasion resistance of the graphene is improved conveniently.
Powder coatings can be classified into thermoplastic and thermosetting powder coatings, wherein thermosetting powder coatings have the advantage of being well leveled and strongly coated compared to thermoplastic powder coatings, but cannot be reused inevitably, which is the most hard lesion limiting its application.
