On April 2, 2018, the review meeting of the "Nanotechnology Terminology Part 13: Graphene and Related Two-dimensional Materials" standard (draft for review) was successfully held in Beijing. 30 experts from 21 units across the country, including National Standards Committee, National Nanoscience Center, Metallurgical Standards Information Institute, Taizhou Juna New Energy Co., Ltd., Southeast University, Institute of Semiconductors, Chinese Academy of Sciences, and Taizhou Graphene Research and Testing Platform Co., Ltd. participated in the event. Meeting. The delegates listened to the report of the standard drafting unit, Dr. Liang Zheng from Taizhou Juna New Energy Co., Ltd. on behalf of the standard preparation working group, and carefully reviewed the content of the standard (draft for review) one by one, and unanimously agreed that the standard passed the review

The standard was drafted by Taizhou Juna New Energy Co., Ltd. and other units, and is the first national standard in my country's graphene industry. This standard (submission draft) is equivalent to the international standard ISO TS 80004-13 Nanotechnologies Vocabulary Part 13 Graphene and related two-dimensional 2D materials, which reflects the technical content of the original standard. The technical content of the adopted standard is adapted to the current technical level, and the technical regulations are advanced and reasonable. This standard will provide the basic basis for unifying technical terms in the fields of production, application, inspection, circulation, and scientific research of graphene and related two-dimensional materials. important foundations and prerequisites. The release and implementation of this standard will further be in line with international standards, which is conducive to promoting the healthy and orderly development of graphene and related two-dimensional materials industry

Graphene is a single layer of carbon atoms that is composed of one carbon atom combined with three neighboring carbon atoms to form a honeycomb structure. Due to its many excellent properties (such as electrical and thermal conductivity), graphene has great application prospects, and it has attracted great academic and commercial interest in the past decade. Recently, other materials with graphene-like structures have also shown good performance, for example, monolayer and few-layer hexagonal boron nitride (hBN), molybdenum disulfide (MoS2), tungsten diselenide (WSe2), silicene ( Silicene), germanene (germanene), and layered assemblies of mixtures of these materials. The thickness of these materials is limited to nanometers or less and consists of one to several layers. These materials are called two-dimensional (2D) materials because one dimension is at the nanoscale or smaller, while the other two dimensions are usually larger than the nanoscale. Layered materials are composed of two-dimensional layers that form a three-dimensional structure through weak stacking or weak bonding. It should be pointed out that real 2D materials do not have to have flat topography, warp structures can exist, and aggregates and agglomerates with different topographies can be further formed. Two-dimensional materials are an important part of nanomaterials. In recent years, breakthroughs have been made in the preparation, detection, research and application of graphene and related two-dimensional materials, and various new technologies and new products have emerged one after another, indicating that graphene and related two-dimensional materials have been in the key to industrialization from the laboratory stage. As a typical two-dimensional material, the industrialization and standardization of graphene has important reference value and reference significance for the development of other two-dimensional materials.

It is reported that Taizhou Juna New Energy Co., Ltd. (hereinafter referred to as Juna) was established in 2010 and is one of the earliest enterprises engaged in graphene research and application in China. Since the establishment of the company, Juna has attached great importance to the standardization of graphene. Working Committee CIGIU/ISTC Secretariat undertakes the unit. In 2014, with the support and guidance of the Taizhou Municipal People's Government of Jiangsu Province and the Taizhou Municipal Bureau of Quality and Technical Supervision, Juna also proposed to the National Standardization Management Committee to formulate graphene technology through the Jiangsu Provincial Bureau of Quality and Technical Supervision and the National Nanotechnology Standardization Technical Committee. Task Application for National Standards for Terminology. In October 2014, the National Standardization Administration officially approved the project in the first batch of national standard formulation and revision plans in 2014. The project name is "Terminology and Definition of Graphene Materials", and the project plan number is 20140893-T- 491. During the preparation of this standard, ISO/TS 80004-13:2017 "Nanotechnology Terminology Part 13: Graphene and related two-dimensional materials" was officially promulgated. After research, this project is adjusted to be equivalent to ISO/TS 80004-13:2017, and it is proposed to adjust the project name to "Nanotechnology Terminology Part 13: Graphene and Related Two-dimensional Materials".
