On April 6th, the national standard (draft for comments on the terminology, definition and code of graphene materials), which has received much attention from the industry, was officially announced on the official website of the China National Standardization Administration Committee on the 5th and will be open to the public for comments within one month. . This marks an important progress in the development of China's first graphene national standard. Dai Shifeng, secretary-general of the Nanomaterials Branch of the National Nanotechnology Standardization Technical Committee and senior engineer of the Metallurgical Industry Information Standards Institute, introduced the national standard for graphene materials, which defines the term “what is graphene†and related materials. It is the first time in China to systematically propose a construction scheme for the graphene terminology system.
It is worth noting that this standard creatively proposes the “product code of graphene materialsâ€. The code consists of the basic core information of graphene materials. By letting graphene companies actively mark some basic information of graphene materials in a self-declared way, the public can see the basic quality of graphene materials at a glance.
It is understood that in recent years, the industry has paid close attention to graphene, and graphene research and industrialization have been rapidly developed. However, for what is graphene, due to the lack of uniform standards in the country, it has always been mixed, making the market a mixed bag.
"The formulation and implementation of this standard provides a unified technical language for the exchange between industry and academia. On the other hand, the introduction of the product code will also provide an effective means for the industry to self-monitoring and self-discipline, avoiding individual falsehoods. Propaganda behavior is conducive to guiding and promoting the healthy and orderly development of China's graphene industry." Dai Shifeng said.
He believes that the solicitation of opinions on national standards is not only a process of soliciting opinions from all walks of life, but also improving the standard technical content. It is also an important opportunity to publicize the technical content of the draft standards to the society.
In addition, the first draft international standard for graphene submitted by China has recently been approved by the International Organization for Standardization and is expected to be approved in the second half of this year. This will provide a good opportunity for China's graphene industry to actively participate in the formulation of international technical rules, and lay a solid foundation for the future development of China's graphene industry.
Graphene materials are novel nanomaterials with excellent properties such as electricity, heat, light and strength. They have shown good application prospects in energy equipment, transportation, aerospace and other fields. At present, the United Kingdom, the United States, South Korea and other countries are embarking on the industrialization of graphene, and China is also one of the countries with the most active research and application development of graphene. The data shows that China has applied for the largest number of graphene patents, which has exceeded 2,200, accounting for one-third of the world.
