【Deep coating society, popular science knowledge】Borographene is a new two-dimensional material with great potential for future development

Borographene, a two-dimensional material, is a graphene-like single-layer planar atomic structure formed by the element boron, which is a thin film
with only one atomic thickness.
Borographene is synthesized artificially, predicts a variety of structures, has unique properties, exhibits many metal properties, especially electronic properties, is a new two-dimensional material
.

In the mid-90s of the 20th century, the existence of boromoene was first predicted theoretically, and in 2015, boronene was confirmed in the laboratory, due to its high polymorphism, boromoene predicted the existence of multiple structures
.
Borographene has the characteristics of
high stability, good mechanical properties, high hardness and high Young's modulus.
Compared with graphene, which has many research results and continuous expansion of application demand, the mechanical properties and hardness of boronene are close to it, and Young's modulus is higher in the horizontal direction and lower in the vertical direction, and there are performance differences
.

Boron preparation is different from graphene, graphite is formed by stacking multiple layers of two-dimensional layers, peeling off a single layer of two-dimensional layers to obtain graphene, while boron is not formed by two-dimensional layer stacking, naturally does not exist, can not be obtained by peeling, must be synthesized
.
At present, the preparation of boronene mainly adopts the physical vapor deposition method, under ultra-advanced vacuum conditions, boron gasification, and the particles produced by gasification are deposited on the substrate (generally using a metal substrate) to form a single layer of film, thereby obtaining boronene.

According to the "2022-2027 China Borographene Industry Market In-depth Research and Development Prospect Forecast Report" released by Xinsijie Industry Research Center, compared with graphene, boronene has higher strength and higher structural flexibility, and can be widely used in sensors, solar cells, energy storage, flexible electronics, catalytic chemistry and other fields
.
Especially in the field of solar cells, borometry can be used as a new and more powerful anode material in the manufacture of
lithium-ion batteries.
At present, a variety of structures of boromoene have been prepared in the laboratory, mainly polymorphic boromorphene, in practical applications, monomorphic borographene is more in demand, so the research of boronene technology is still deepening
.

In January 2022, a team from Yale University in the United States synthesized micron-sized boroktene single crystals on the surface of square lattice Cu(100), which is a different borographene crystal form from previous studies, and found that the structure
of boromoene in the plane can be designed by the selection of substrate and surface materials.
In addition to Yale University, borographene related research institutes at home and abroad include Tsinghua University in China, Xiamen University in China, Brown University in the United States, Northwestern University in the United States, State University of New York at Stony Brook, Argonne National Laboratory, etc
.

Industry analysts of Xinsijie said that in order to promote the upgrading of industrial technology, the global market has paid high attention to the research and application of new materials, the government and capital have continuously increased investment in the field of new materials research, high-performance new materials have been continuously developed, and the speed of commercialization has accelerated
。 As a new two-dimensional material, borographene has excellent electronic properties, has great development potential in electronics, energy and other industries, in the short term because it is still in the research stage, its application market has not yet formed, but in the long run, compared with graphene, it has a broad market space
