MAX materials and MXene materials are new two-dimensional materials who have attracted much attention recently, with excellent physical, chemical, and mechanical properties, and also have shown broad application prospects in many fields. This is an in depth introduction to the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is a layered carbon nitride inorganic non-metallic material composed of M, A, X elements on the periodic table, collectively called “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the main group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, the 3 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 widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
