MAX materials and MXene materials are new two-dimensional materials who have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in many fields. This is an in depth overview of 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 in the periodic table, collectively referred to 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 composed of M, A, X, the three components of the alternating composition arrangement, with hexagonal lattice structure. Due to their electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, they may be widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding as well as other fields.
