MAX materials and MXene materials are new two-dimensional materials who have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in lots of fields. The following is a comprehensive 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 comprising 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 main group elements, like aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, three of the 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 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 actually a new type of layered carbon nitride inorganic non-metallic material with 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 to the transition metal, A means the main-group elements, and X refers back to the aspects of C or N. The MXene material is a graphene-like structure obtained by 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.
