MAX materials and MXene materials are new two-dimensional materials that have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in numerous fields. This is a detailed introduction to the properties, applications, and development trends of MAX and MXene materials.
What exactly is MAX material?
MAX phase material is really a layered carbon nitride inorganic non-metallic material composed of M, A, X elements on the periodic table, collectively known as “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the primary group elements, like aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is made up of M, A, X, three of the elements 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, they are commonly 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 actually a new form of layered carbon nitride inorganic non-metallic material using the conductive and thermal conductive qualities of metal, comprising three elements with the molecular formula of Mn 1AXn (n=1, 2 or 3), where M means the transition metal, A means the main-group elements, and X refers back to the aspects of C and 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.
