Max Phase Materials in Biomedical Device Development

MAX materials and MXene materials are new two-dimensional materials who have attracted much attention lately, with excellent physical, chemical, and mechanical properties, and possess shown broad application prospects in numerous fields. This is a detailed introduction to the properties, applications, and development trends of MAX and MXene materials.

Precisely What is MAX material?

MAX phase material is actually a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements on the periodic table, collectively referred to as “MAX phase”. M represents transition metal elements, like titanium, zirconium, hafnium, etc., A represents the key 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 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 are 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, composed 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 to the components of C and 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. MAXenes and MXenes are novel two-dimensional nanomaterials made up of carbon, nitrogen, oxygen, and halogens.
