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 comprehensive guide 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 comprising M, A, X elements around the periodic table, collectively referred to 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 is composed of M, A, X, the three components 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 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 a new form of layered carbon nitride inorganic non-metallic material using the conductive and thermal conductive qualities of metal, comprising three elements using the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers back to the transition metal, A refers to the main-group elements, and X refers to the components of C and N. The MXene material is a graphene-like structure obtained through the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. MAX phases are novel two-dimensional nanomaterials composed of carbon, nitrogen, oxygen, and halogens.
