MAX materials and MXene materials are new two-dimensional materials who have attracted much attention recently, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in many fields. The following is an in depth overview of the properties, applications, and development trends of MAX and MXene materials.

Precisely What is MAX material?

MAX phase material is a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements in the periodic table, collectively referred to as “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the main 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. Because of the electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, these are widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding as well as other fields.
