MAX materials and MXene materials are new two-dimensional materials that have attracted much attention in recent years, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in numerous fields. The following is a detailed introduction to the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is actually a layered carbon nitride inorganic non-metallic material composed of M, A, X elements in the periodic table, collectively called “MAX phase”. M represents transition metal elements, like 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, the three components of the alternating composition arrangement, with hexagonal lattice structure. Because of their 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 as well as other fields.
Properties of MAX material
MAX material is a new form of layered carbon nitride inorganic non-metallic material using the conductive and thermal conductive qualities of metal, composed of three elements with the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers to the transition metal, A refers back to the main-group elements, and X refers back to the elements of C or N. The MXene material is really a graphene-like structure obtained by 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.
