MAX materials and MXene materials are new two-dimensional materials that 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 an in depth 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 consisting of M, A, X elements on the periodic table, collectively referred to as “MAX phase”. M represents transition metal elements, including titanium, zirconium, hafnium, etc., A represents the main group elements, including aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is made up of M, A, X, the three aspects of the alternating composition arrangement, with hexagonal lattice structure. Due to their electrical conductivity of metal and 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 and other fields.
Properties of MAX material
MAX material is actually a new kind of layered carbon nitride inorganic non-metallic material with 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 to the transition metal, A refers to the main-group elements, and X refers to the components of C and/or N. The MXene material is actually 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 made up of carbon, nitrogen, oxygen, and halogens.
