Since graphene won the Nobel Prize in Physics in 2010, scientists and industry have been enthusiastically chasing graphene. While chasing graphene, a large number of two-dimensional materials such as graphene have also been discovered, how to accurately define the development of related materials industry. The reporter learned from Taizhou Juna New Energy Co., Ltd. on the 17th that the company's first graphene national standard GB/T 30544.13-2018: "Nano-technical terminology 13: graphene and related two-dimensional materials" was officially released. . This standard is also the first national standard in the field of two-dimensional materials.

The two-dimensional material family of graphene-like materials involves a large span of disciplines, a wide range of fields, and a wide variety of species. It has always presented a multi-point flowering, new phenomenon, and new application frequently. Two-dimensional materials are one of the most cutting-edge research applications in the world, covering printed electronics, flexible electronics, supercapacitors, solar cells, quantum dots, sensors, semiconductor manufacturing, etc., with excellent mechanical, thermal and optical properties. The realm of disruptive innovation in the field.

According to the definition of national standards, it consists of one or several layers, in which the atoms in each layer are tightly bonded to the adjacent atoms in the layer, and one dimension (ie its thickness) is at the nanometer or smaller scale, and the other two Dimensions are usually larger-scale materials called two-dimensional materials.

What are the excellent properties of 2D materials? Since the surface atoms of a single-layer two-dimensional material are almost completely exposed, atomic utilization is greatly improved compared to bulk materials. The band structure and electrical properties can be more easily regulated by thickness control and element doping. Therefore, the two-dimensional material is more conducive to chemical modification, and is more conducive to electron transfer. At the same time, its flexibility and transparency are high, and it is attractive in the fields of wearable smart devices and flexible energy storage devices.

China's first national standard for graphene and two-dimensional materials was drafted by Taizhou Junner New Energy Co., Ltd. and Southeast University. The former was established in 2010 and is the first company in China to engage in research, testing, application and standardization of graphene. One.
