MAX materials and MXene materials are new two-dimensional materials which have attracted much attention recently, with excellent physical, chemical, and mechanical properties, and also have shown broad application prospects in lots of fields. This is a detailed guide to the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is really a layered carbon nitride inorganic non-metallic material comprising 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 primary 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 elements 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, these are commonly used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding as well as other fields.
