Information released on the official website of ISO: the international first "carbon nanotube slurry" international standard-ISO / TS 19808: 2020 "Nanotechnologies-Carbon nanotube suspensions-Specification of characteristics and measurement methods" (Nanotechnology-carbon nanotube slurry —Technical specifications for characterization and measurement methods) was officially released on March 2 for use by countries around the world. The international standard was jointly led by Dr. Mao Ou of China JSTN Nanotechnology Co., Ltd. and Dai Shifeng, senior secretary of Zhongguancun Huaqing Graphene Industry Technology Innovation Alliance, as the project leader, responsible for the technical ideas of the international standard. Text writing work. Experts from enterprises and scientific research institutes in Japan, the United States, Germany, South Korea, India, Iran and other countries, as well as experts from the domestic team of Professor Wei Fei of Tsinghua University and carbon nanotube slurry user companies-HFGX Hi-Tech Power Energy Co., Ltd. The standard provides technical support and program contributions.
Carbon nanotubes are a new type of carbon nanomaterials with excellent electrical, thermal and mechanical properties. Since the beginning of this century, the industrial preparation technology of carbon nanotubes has made breakthroughs and gradually matured, and has been widely used in new energy, composite materials, electronic devices, biomedicine and other fields. How to ensure the dispersion of carbon nanotubes is one of the biggest technical difficulties in application. JSTN's first carbon nanotube slurry product form in the world not only effectively solves the problem of dispersion of carbon nanotubes, but also solves transportation and operation. Environmental health and safety protection problems in the process. At present, the carbon nanotube slurry products have become the mainstream form of supply for the international carbon tube industry. Enterprises in China, Japan, South Korea, Germany, France, Belgium, the United States, and Russia have provided carbon nano-slurry products in batches and formed a competitive situation. The comprehensive technical level of carbon nanotube products made in China is internationally leading, with an international market share of nearly 30%.
This international standard is based on the comprehensive production level and evaluation method of carbon nanotube slurry products at home and abroad. Based on the national standard of China's GB / T 33818-2017 "Carbon Nanotube Conductive Paste", carbon nanotubes and pastes are established. The core evaluation system and testing method guide, focusing on the nano-characteristics, application and functionality of carbon nanotube slurry. The formulation of this international standard will surely further promote the development and application of carbon nanotube materials in various fields, expand the application field of carbon nanotube materials, and at the same time further increase the visibility and better quality of carbon nanotube slurry products made in China. Provide international customers with high-quality carbon nanotube products and provide solid technical standard support.
The official release of this international standard marks that JSTN has become the double material host of the "carbon nanotube slurry" national and international standards. JSTN company is committed to the research and development, production and application development and sales of carbon nanotubes and graphene. The commercial application areas are mainly lithium battery conductive paste applications; it has patents related to the preparation of carbon nanotubes and carbon nanotube batch Production expertise. Since its establishment, the company has been actively participating in and leading the formulation of a number of national and group standards for carbon nanotubes and graphene materials. It is both an active contributor and a beneficiary of the standard.
The Zhongguancun Huaqing Graphene Industry Technology Innovation Alliance (hereinafter referred to as the Union) is a social group registered in accordance with law with the support of the Zhongguancun Management Committee in 2015. The existing member units of the alliance include scientific research, preparation, application, testing and trade related to domestic mainstream graphene materials and other new materials. In recent years, the Alliance has organized a number of group standards and international standards in graphene, nanomaterials and other fields. It has become the earliest domestic standardization organization for graphene standardization, the largest number of participants, and the most influential industry.
