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 possess shown broad application prospects in lots of fields. The following is a detailed 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 composed of M, A, X elements in the periodic table, collectively called “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the primary group elements, including aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer consists 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.
