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 detailed introduction to the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is really a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements in the periodic table, collectively known as “MAX phase”. M represents transition metal elements, including titanium, zirconium, hafnium, etc., A represents the key group elements, including aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer consists of M, A, X, the 3 elements of the alternating composition arrangement, with hexagonal lattice structure. Because of the 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 and other fields.
Properties of MAX material
MAX material is really a new kind of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, comprising three elements with all 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 means the aspects of C or 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. MAXenes and MXenes are novel two-dimensional nanomaterials made up of carbon, nitrogen, oxygen, and halogens.
