Graphene-like materials have broad application prospects and global research continues to deepen

Graphene-like materials refer to materials with a two-dimensional single-layer or few-layer structure. The layers of graphene-like materials are mostly bonded by van der Waals forces, so they are also called van der Waals type crystals. Types of graphene-like materials include layered van der Waals solid materials, layered ionic solid materials, Group IV graphene-like materials, Group IV element compounds, Group III-V compounds, etc. Subdivided materials include hexagonal boron nitride, Molybdenum disulfide, titanium disulfide, silicene, germanene, phosphorene, etc. Among them, silicene and molybdenum disulfide have been studied more in recent years.

Graphene is a typical two-dimensional nanomaterial with excellent optical, electrical, and mechanical properties. In recent years, with its excellent performance, the application fields of graphene have been increasingly expanded. However, graphene also has zero band gap, low light absorption rate, and high cost. Problem, its large-scale application is subject to certain limitations. Graphene-like materials are similar to graphene. They not only have the excellent properties of graphene, but also make up for the performance shortcomings of graphene and expand the practical application scope of graphene.

According to the “2022-2026 China Graphene-like Materials Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center It shows that two-dimensional materials are the basic materials of micro-nano devices, and the emergence of graphene-like materials provides new ideas for the large-scale production and high-quality development of micro-nano devices. As the forefront of research in the field of new materials, graphene-like materials have attracted the deployment of many companies and research institutions. In China, there are Tsinghua University, Shandong Institute of Advanced Technology, Jiangsu Xianfeng Nanomaterials, Yunnan University, etc.

Silicene is a single-atomic layer silicon crystal film that can grow on the surface of silver, iridium and other substrates. Silicene is a silicon material and a new silicon allotrope, so the silicene device manufacturing process is compatible with silicon-based processes. Silicene can be prepared by epitaxial growth on boride surfaces or by deposition and growth on Ag single crystal surfaces. Global silicene research is still in its infancy, but it has shown good application potential in microelectronics, nanoelectronics and other fields.

Molybdenum disulfide is an inorganic compound composed of molybdenum and sulfur. Molybdenum disulfide is the main component of molybdenite. Globally, molybdenum disulfide production capacity is mainly concentrated in the United States. Related production companies include Clemax Molybdenum, Dow Corning, GFS Chemicals, and Noah Technologies Corp; domestically, molybdenum disulfide The molybdenum market is in the stage of development and improvement, and relevant manufacturers include Tianjin Sifang Chemical, Luoyang Luanchuan Molybdenum, Jinduicheng Molybdenum, etc.

Industry analysts said that research on graphene-like materials originated from graphene. Similar to graphene, graphene-like materials have multiple advantages. performance, it shows broad application prospects in catalysts, batteries, quantum communications, semiconductors, medical, aerospace and other fields. At present, research on graphene-like materials in my country is still in its infancy, and research institutions and enterprises are constantly increasing. In the future, driven by in-depth research and technological empowerment, the market applications of graphene-like materials will increasingly expand.
