MAX materials and MXene materials are new two-dimensional materials that have attracted much attention in recent years, with excellent physical, chemical, and mechanical properties, and have shown broad application prospects in many fields. The following is a detailed introduction to the properties, applications, and development trends of MAX and MXene materials.
 
What is MAX material?
MAX phase material is a layered carbon nitride inorganic non-metallic material consisting of M, A, X elements on the periodic table, collectively known as "MAX phase". M represents transition metal elements, such as titanium, zirconium, hafnium, etc., A represents the main group elements, such as aluminum, silicon, germanium, etc., X represents carbon or nitrogen. MAX-phase materials, each atomic layer is composed of M, A, X, the three elements 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 are 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 a new type of layered carbon nitride inorganic non-metallic material with 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 to the main-group elements, and X refers to the elements of C and/or N. The MXene material is a graphene-like structure obtained by the MAX phase treatment with two-dimensional transition metal carbides, nitrides, or carbon-nitrides.MAX/MXene materials are novel two-dimensional nanomaterials composed of carbon, nitrogen, oxygen, and halogens.
 
Applications of MAX materials
(1) Structural materials: the excellent physical properties of MAX materials make them have a wide range of applications in structural materials. For example, Ti3SiC2 is a common MAX material with good high-temperature performance and oxidation resistance, which can 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 example, some MAX materials have good electromagnetic shielding properties and conductivity and can be used to manufacture electromagnetic shielding covers, coatings, etc. In addition, 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 can be used in energy materials. For example, K4(MP4)(P4) is one of the MAX materials with high ionic conductivity and electrochemical activity, which can be used as a raw material to manufacture solid-state electrolyte materials and electrochemical energy storage devices.
 
What are MXene materials?
MXene materials are a new type of two-dimensional nanomaterials obtained by MAX phase treatment, similar to the structure of graphene. The surface of MXene materials can interact with more functional atoms and molecules, and a high specific surface area, good chemical stability, biocompatibility, and tunable physical properties, etc, characterize them. The preparation methods of MXene materials usually include the etching treatment of the MAX phase and the self-templating method, etc. By adjusting the chemical composition and structure of MXene materials, the tuning of physical properties such as 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 consisting of metal and carbon or nitrogen elements. These materials have excellent physical properties, such as high electrical conductivity, high elasticity, good oxidation, and corrosion resistance, etc., as well as good chemical stability and the ability to maintain high strength and stability at high temperatures.
 
Applications of MXene materials
(1) Energy storage and conversion: MXene materials have excellent electrochemical properties and ionic conductivity and are widely used in energy storage and conversion. For example, MXene materials can be used as electrode materials in supercapacitors and lithium-ion batteries, improving electrode energy density and charge/discharge speed. In addition, MXene materials can also be used as catalysts in fuel cells to improve the activity and stability of the catalyst.
 
(2) Electromagnetic protection: MXene materials have good electromagnetic shielding performance, and conductivity can be used in electromagnetic protection. For example, MXene materials can be used as electromagnetic shielding coatings, electromagnetic shielding cloth, and other applications in electronic products and personal protection, improving the effectiveness and stability of electromagnetic protection.
 
(3) Sensing and detection: MXene materials have good sensitivity and responsiveness and can be used in sensing and detection. For example, MXene materials can be used as gas sensors in environmental monitoring, which can realize high sensitivity and high selectivity detection of gases. In addition, MXene materials can also be used as biosensors in medical diagnostics and other fields.
