MAX materials and MXene materials are new two-dimensional materials who have attracted much attention in recent years, with excellent physical, chemical, and mechanical properties, and also have shown broad application prospects in numerous fields. The following 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 around the periodic table, collectively called “MAX phase”. M represents transition metal elements, including 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 made up of M, A, X, the three aspects of the alternating composition arrangement, with hexagonal lattice structure. Because of their electrical conductivity of metal and strength, high-temperature resistance and corrosion resistance of structural ceramics, they are widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
Properties of MAX material
MAX material is a new type of layered carbon nitride inorganic non-metallic material with the conductive and thermal conductive qualities of metal, consisting of three elements using the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers back to the transition metal, A means the main-group elements, and X refers to the components of C and N. The MXene material is a graphene-like structure obtained from the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MXenes material are novel two-dimensional nanomaterials composed of carbon, nitrogen, oxygen, and halogens.
