The market prospect of Mxene is good, but the current degree of industrialization is low

Two-dimensional transition metal carbon/nitride (MXene) is a two-dimensional nanomaterial with a structure similar to graphene. It is generally prepared by selectively etching away the A atoms in the MAX phase. The general structural formula of MXene is Mn+1XnTx (n=1, 2, 3), where M is a transition metal (M=Ti, Sr, V, Cr, Ta, Nb, Zr, Mo, etc.), and X represents C or N , Tx represents the surface terminal group (-O, -OH, -Cl or -F, etc.). Up to now, more than 30 different MXenes have been synthesized, common ones such as Ti3C2, Ti3AlC2, etc.

There are many types of MAX phase products, and a variety of MXenes with different properties can be obtained by using the MAX phase. According to different product performance, product structure, product form, etc., MXene can be divided into different products. Such as etched and unetched MXene, single-layer and multi-layer MXene, powdered and liquid MXene, etc. MXene is a new type of transition metal carbon/nitride two-dimensional nanolayered material. Its unique physical and chemical properties make it have good application prospects in many fields such as energy storage and conversion, sensors, and multifunctional polymer composite materials in recent years. .

The development time of global MXene materials is short. In 2011, the research group of Professors Gogotsi and Barsoum of Drexel University in the United States obtained MXene materials for the first time through chemical corrosion method. The first MXene-related project in China was funded by the National Foundation of China in 2012 by Henan University of Technology. It has only been developed for about 10 years, and the industry is still in its early stages of development, with very low maturity.

From the perspective of industrialization level, due to the short development time of the domestic MXene industry, most companies and research institutions are still in the technology research and development and optimization stage. In addition, the barriers to entry in the MXene industry are high. Although there are currently more companies involved in R&D, the actual production companies Very few, some enterprise products are still in the experimental stage, the level of industrialization in the industry is relatively low, and there is no industrial production equipment. According to the“China MXene Industry Market In-depth Research and Development Prospects Forecast Report 2022-2026” released by the Industrial Research Center, in 2021, China’s MXene output is only 8.01kg.

From a technical point of view, China’s research on MXene materials has made great progress, but there are still many basic theoretical and technical bottlenecks that have not been resolved. For example, the role of cation vacancies in MXene in improving its energy storage is not clear, etc. , it is still necessary for relevant enterprises and scientific research institutes to increase investment in research and development to solve the technical problems existing in the industry.

From the perspective of industry development prospects, MXene material is a two-dimensional nanomaterial with a structure similar to graphene. Compared with graphene, MXene material not only inherits the excellent properties of traditional two-dimensional nanomaterials, but also exhibits graphene-like performance. And the highly conductive surface of metal (~8000S/cm), it also has high energy density (the redox reaction of surface transition metal and electrolyte ions can produce high specific capacitance) and good electromagnetic shielding properties. Good development prospects.
