MAX materials and MXene materials are new two-dimensional materials that have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in numerous fields. This is a detailed guide to the properties, applications, and development trends of MAX and MXene materials.
Precisely What is MAX material?
MAX phase material is really a layered carbon nitride inorganic non-metallic material composed of M, A, X elements in the periodic table, collectively called “MAX phase”. M represents transition metal elements, including titanium, zirconium, hafnium, etc., A represents the key group elements, like aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, the three elements of the alternating composition arrangement, with hexagonal lattice structure. Due to their electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, these are commonly used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
