MAX materials and MXene materials are new two-dimensional materials that have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in many fields. The following is a comprehensive overview of the properties, applications, and development trends of MAX and MXene materials.
What exactly is MAX material?
MAX phase material is actually a layered carbon nitride inorganic non-metallic material comprising M, A, X elements on the periodic table, collectively known as “MAX phase”. M represents transition metal elements, including 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 consists of M, A, X, the 3 components of the alternating composition arrangement, with hexagonal lattice structure. Because of their electrical conductivity of metal and high strength, high-temperature resistance and corrosion resistance of structural ceramics, they may be popular in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding along with other fields.
Properties of MAX material
MAX material is really a new form of layered carbon nitride inorganic non-metallic material with all the conductive and thermal conductive qualities of metal, consisting of three elements with the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers to the transition metal, A refers back to the main-group elements, and X refers to the components of C or N. The MXene material is 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 composed of carbon, nitrogen, oxygen, and halogens.
