Academicians In New Material Field Evaluate Graphene Polymerization In Situ: "A Disruptive Breakthrough"

What is graphene?
What does graphene have to do with our life?
Will this magical material wear on us?
The answer may be in the field of new materials.
Graphene is the world's thinnest, hardest and best conductive nanomaterials. It is known as the most disruptive new material in twenty-first Century. With the breakthroughs in low cost, high performance and large-scale application technology, graphene will set off an industrial revolution sweeping the globe.
Global graphene is in the early stage of industrial breakthrough. In 2018, the global market for graphene was about US $195 million, with an average annual growth rate of over 60% in the past four years. The developed countries have promoted the research and application of graphene to a strategic height, focusing on the strategic and forward-looking layout of graphene patents in basic theoretical research and future high-end applications. The research and application of graphene is of great significance in boosting the transformation and upgrading of traditional industries, supporting the growth and upgrading of new industries, and promoting the upgrading and upgrading of materials industry.

Academician Gan Yong and academician Jiang Shicheng, as the main experts of the "2035 strategic research on new material power", "the strategic research on advanced basic materials and powerful countries", are well aware of the importance of new materials for national strategies.

On the afternoon of August 25th, academician Gan Yong, academician Jiang Shicheng, academician of the Chinese Academy of engineering, deputy director of Li Ji Feng, Department of raw materials industry, Jiangsu Province, Jiangsu Provincial Department of labor and the Promotion Office of Jiangsu Province, Wang Qiongyao, and Liang Qunyi, Deputy Secretary General of the new materials Association of Jiangsu Province, accompanied by the local government leaders, such as Xu Jinlong, Secretary of the town of Dun tou, and mayor of Lu Congjun, and so on, made a special trip to the production base of the "research and application of new graphene modified materials", the production base of Changzhou Hengli Bao new nano Mstar Technology Ltd, the Jiangsu Jiangshan red Chemical Fiber Co., Ltd. conducted an inspection and discussion.

According to the introduction of deputy general manager of Huang Rongqing, manager, the technology of "blending graphene", which is different from the market, is easy to cause problems such as powder leakage, unknown biological toxicity and dyeing limitation. The key technology of in-situ polymerized modified PA6 developed by the enterprise not only realizes the combination of functional graphene chemical bonds and nylon polymer chains, but also greatly reduces the amount of graphene, so that the dispersion of graphene can be completely dispersed in the polymerization process, and fundamentally eliminates the loss of graphene fiber products in subsequent spinning, dyeing, finishing and washing processes. This method pioneered the continuous polymerization process of industrial in-situ polymerization of graphene Polyamide Composites. Based on this, a new production line of 100 tons of functional graphene powder and an annual output of 25 thousand tons of graphene polyamide chips was developed, and a complete set of spinning process packages was developed.

Academician Jiang Shicheng appreciated the samples of 30D/24F graphene PA6FDY filament developed by Hengli Bao technology, especially in the field of high strength, low elongation, bacteriostasis, ultraviolet and far infrared functions. Especially in the same test conditions, the number of wear-resistant PA6 fibers in situ polymerization was more than 3 times higher than that of PA66 fibers. Academician Jiang Shicheng said: "the results of this study are really exciting.

Jiang Yan, chairman and general manager of the company, introduced the development direction of the products and the research and development plan of special fibers, and explained the continuous production line of "modified graphene in-situ polymerization PA6" which will soon be put into operation, and the implementation plan for the preparation and process design of the direct spinning process started next. Graphene in-situ polymerization polyamide 6 is expected to form 25 thousand tons of slicing capacity in 2019, and it is expected that the slicing production will be 3000 tons in that year, of which 2500 tons will be applied to various textile fabrics and 500 tons for plastic products and other fields. In the field of functional textiles, graphene in situ polymerization modified synthetic fiber shows good far-infrared, antibacterial, antibacterial, anti ultraviolet, antistatic, and enhanced functions. In military dress, sports and health clothing, Jiang Yan will also display the process of "modified graphene in-situ polymerization PA6" direct spinning yarn, short fiber, fabric and functional clothing, and smart fashion. Academician Gan Yong said: "If this project is put into operation, it will be a disruptive breakthrough."

Changzhou Hengli Bao nanometre new material company's graphene in-situ polymerization PA6 fiber certification brand - "ENAs TM" can easily achieve the coloring of the original solution, and its antibacterial activity to Staphylococcus aureus, Escherichia coli and Candida albicans exceeds the domestic and international standards. It also has the comprehensive properties of low temperature, far infrared, UV resistance and antistatic. It can be widely used in outdoor sports, fitness, pregnancy, home textiles and other industrial fields; in particular, the enterprise has completed the unique dyeing system, and has also performed well in the bright color system, breaking the market rumors that "graphene fabrics can only be black, gray" wrong interpretation.

In recent years, R & D institutions, enterprises and industrial parks in Jiangsu have jointly developed industrial development. "Graphene industry in Jiangsu" has become the consensus of the industry at home and abroad. Changzhou Hengli Bao nano Mstar Technology Ltd, as a representative enterprise of graphene research and application, has broken through a series of key technologies of material preparation closely combined with the great demand of social development. It has achieved core technological achievements with independent intellectual property rights around the research of graphene modification and "modified graphene in-situ PA6" slice production and spinning technology. At present, nearly 20 invention patents have been obtained from three major fields and six functions, showing the continuous innovation power in the field of graphene new materials. At present, the project of "continuous production of modified graphene in situ polymerization PA6", which is being built by enterprises, takes the lead in breaking through the industrialization extension of new technology of graphene in the world, enlarging the market application scale of new graphene materials, and enhancing the competitiveness of new material supply chain.

The 2.5 hours of communication were heated and in-depth. Academician experts and experts appreciated the technological innovation of Changzhou Hengli Bao nanometer new material technology. During the development of graphene industry in recent years, this project has brought people to the forefront. We have greater confidence in the development of Shi Moxi industry.

Graphene, a magic material, has become a reality. At present, Europe, China and other countries begin to introduce many graphene consumer products. In the near future, as graphene has made new progress in applications such as gas sensors, strain sensors and biosensors, it will have broader prospects in applications such as Internet of things, smart clothing, flexible sensors, wearable devices, and healthy life.
