Max Phase Coatings: Defending Against Extreme Temperatures

MAX materials and MXene materials are new two-dimensional materials which have attracted much attention in recent years, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in numerous fields. The following is a comprehensive 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 comprising M, A, X elements around the periodic table, collectively known as “MAX phase”. M represents transition metal elements, including titanium, zirconium, hafnium, etc., A represents the primary group elements, such as 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, these are popular in high-temperature structural materials, high-temperature antioxidant coatings, high-temperature lubricants, electromagnetic shielding as well as other fields.

Properties of MAX material

MAX material is a new kind of layered carbon nitride inorganic non-metallic material using the conductive and thermal conductive qualities of metal, comprising three elements using the molecular formula of Mn 1AXn (n=1, 2 or 3), where M refers back to the transition metal, A refers back to the main-group elements, and X refers back to the aspects 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 from carbon, nitrogen, oxygen, and halogens.

Uses of MAX materials

(1) Structural materials: the superb physical properties of MAX materials get them to have a wide range of applications in structural materials. For instance, Ti3SiC2 is a kind of MAX material with good high-temperature performance and oxidation resistance, which could be used to manufacture high-temperature furnaces and aero-engine components.

(2) Functional materials: Besides structural materials, MAX materials are also used in functional materials. For instance, some MAX materials have good electromagnetic shielding properties and conductivity and could be used to manufacture electromagnetic shielding covers, coatings, etc. Additionally, some MAX materials also have better photocatalytic properties, and electrochemical properties can be used in photocatalytic and electrochemical reactions.

(3) Energy materials: some MAX materials have better ionic conductivity and electrochemical properties, which may be found in energy materials. As an example, K4(MP4)(P4) is one of the MAX materials with higher ionic conductivity and electrochemical activity, which can be used a raw material to manufacture solid-state electrolyte materials and electrochemical energy storage devices.

What Exactly are MXene materials?

MXene materials really are a new form of two-dimensional nanomaterials obtained by MAX phase treatment, just like the structure of graphene. The top of MXene materials can communicate with more functional atoms and molecules, along with a high specific surface area, good chemical stability, biocompatibility, and tunable physical properties, etc, characterize them. The preparation methods of MXene materials usually range from the etching management of the MAX phase and also the self-templating method, etc. By adjusting the chemical composition and structure of MXene materials, the tuning of physical properties including electrical conductivity, magnetism and optics can be realized.

Properties of MXene materials

MXene materials are a new type of two-dimensional transition metal carbide or nitride materials comprising metal and carbon or nitrogen elements. These materials have excellent physical properties, including high electrical conductivity, high elasticity, good oxidation, and corrosion resistance, etc., along with good chemical stability and the cabability to maintain high strength and stability at high temperatures.

Uses of MXene materials

(1) Energy storage and conversion: MXene materials have excellent electrochemical properties and ionic conductivity and therefore are popular in energy storage and conversion. For instance, MXene materials bring electrode materials in supercapacitors and lithium-ion batteries, improving electrode energy density and charge/discharge speed. In addition, MXene materials could also be used as catalysts in fuel cells to enhance the action and stability of the catalyst.

(2) Electromagnetic protection: MXene materials have good electromagnetic shielding performance, and conductivity can be used in electromagnetic protection. For instance, MXene materials can be used electromagnetic shielding coatings, electromagnetic shielding cloth, as well as other applications in electronic products and personal protection, enhancing the effectiveness and stability of electromagnetic protection.

(3) Sensing and detection: MXene materials have good sensitivity and responsiveness and may be used in sensing and detection. For instance, MXene materials bring gas sensors in environmental monitoring, which can realize high sensitivity and selectivity detection of gases. Additionally, MXene materials can also be used as biosensors in medical diagnostics as well as other fields.
