MAX materials and MXene materials are new two-dimensional materials who have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and also have shown broad application prospects in numerous fields. The following is a comprehensive 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 consisting of M, A, X elements around the periodic table, collectively known as “MAX phase”. M represents transition metal elements, like 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 composed of M, A, X, three of the 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 and other fields.
Properties of MAX material
MAX material is actually a new kind of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, consisting of three elements using the molecular formula of Mn 1AXn (n=1, 2 or 3), where M means the transition metal, A refers back to the main-group elements, and X refers back to the components of C and/or N. The MXene material is actually a graphene-like structure obtained through the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides. Max Phase material are novel two-dimensional nanomaterials made up of carbon, nitrogen, oxygen, and halogens.
