MAX materials and MXene materials are new two-dimensional materials that have attracted much attention recently, with excellent physical, chemical, and mechanical properties, and 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.
Precisely What is MAX material?
MAX phase material is actually a layered carbon nitride inorganic non-metallic material composed of M, A, X elements in the periodic table, collectively known as “MAX phase”. M represents transition metal elements, like 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 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, they are widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding and other fields.
