MAX materials and MXene materials are new two-dimensional materials which have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in many fields. The following is a detailed overview of the properties, applications, and development trends of MAX and MXene materials.
What is MAX material?
MAX phase material is actually a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements around the periodic table, collectively referred to as “MAX phase”. M represents transition metal elements, including titanium, zirconium, hafnium, etc., A represents the main group elements, like aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is made up 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 may be widely used in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
