MAX materials and MXene materials are new two-dimensional materials who have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and also have shown broad application prospects in many fields. The following is a comprehensive guide to the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is 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, 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 made up 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, these are popular 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 type of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, composed of three elements using 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 means the components of C and/or N. The MXene material is really a graphene-like structure obtained from the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MAX Phases and MXenes are novel two-dimensional nanomaterials made from carbon, nitrogen, oxygen, and halogens.
