MAX materials and MXene materials are new two-dimensional materials that have attracted much attention recently, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in numerous fields. This is a comprehensive guide to the properties, applications, and development trends of MAX and MXene materials.
Precisely What is MAX material?
MAX phase material is actually a layered carbon nitride inorganic non-metallic material composed of M, A, X elements on the periodic table, collectively called “MAX phase”. M represents transition metal elements, such as titanium, zirconium, hafnium, etc., A represents the primary group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, three of the components of the alternating composition arrangement, with hexagonal lattice structure. Because of the electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, these are widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding and other fields.
Properties of MAX material
MAX material is a new type of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, comprising three elements using the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers to the transition metal, A means the main-group elements, and X refers to the aspects of C and N. The MXene material is a graphene-like structure obtained through the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MAX phases are novel two-dimensional nanomaterials composed of carbon, nitrogen, oxygen, and halogens.
