Professor Sun Xiaogang's long-term research on carbon nanotubes includes the synthesis, modification and filling of carbon nanotubes and the application of carbon nanotubes in the fields of electromagnetic shielding, wave absorption, lithium ion batteries and composite materials. Chairman and general manager of Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. In 1999, it began to produce carbon nanotubes and provided them to the whole world. In 2000, it successfully developed a 5kg carbon nanotube device per day. In 2001, it established Nanchang Sun nanotechnology Co., Ltd. and served as the chairman and CEO, the company is one of the first several companies in the world to industrialize the production of carbon nanotubes (at that time there were only 7 companies in the world that could provide carbon nanotubes products), and the production of carbon nanotubes reached the ton level, users all over the world.
"The Lead color fades out and leaves its true color, the big waves and sand rush to see gold at first". After 20 years of persistent research, the expert technical team led by Professor Sun Xiaogang of KELAIWEI company finally made me take the lead in the related technical fields of carbon nanomaterials. Our carbon nanomaterials products have been tested by the actual cooperative applications of cooperative customers in more than 60 countries around the world, and are highly praised by customers for their high performance and stability.
KELAIWEI company focuses on the research and development and production of high-end nanomaterials products, processes and production line equipment. KELAIWEI nano carbon material company owns the technology patent invention and advanced production research and development management system which is the mainstay in the industry, and its products have been exported to more than 60 countries in the world. Our company has great technical advantages in the high-end nanomaterials industry. There are production bases and research and development centers in Henan and Jiangxi.
The R & D department of KELAIWEI company reported good news again that our scientific research personnel have made further achievements in the application and research of carbon nanometer paste. This product is widely used, such as the application of polymer composite materials, the application of heating paper, production and manufacture of high-end lithium ion power batteries of high-strength wear-resistant rubber tires of vehicles, therefore, Henan KELAIWEI Nano Carbon Material Co., Ltd firmly believes that the application fields of whisker carbon nanotubes are broad and the market prospect is huge.
Carbon nanotubes are conductive agents with high conductivity in the new era, which can be applied to high-end lithium battery manufacturing industry. Carbon nanotubes not only do not hinder the transmission of ions, but also because of their huge aspect ratio, they can obtain very good conductivity with only a small amount of filling. KELAIWEI company learned that more and more battery manufacturers have been using this material.
Conductive agents are widely used. What is the future development of conductive agents? Conductive agents include traditional conductive agent materials represented by carbon black, and in recent years, new high-end conductive agent materials represented by carbon nanotubes have been developed. Various conductive agents are constantly appearing in the laboratory. The new conductive agent graphene has not been applied on a large scale, because its cost is too high, but its performance is far higher than that of traditional conductive agents such as carbon black. With the arrival of mass production of graphene, it is bound to be widely used in the future.
The top-down method is used to prepare carbon nanoparticles. The preparation method of ordinary carbon nanotubes adopts the method of preparing solid catalyst first, and then high temperature cracking under the action of reducing gas. The solid catalyst is generally used as catalyst, the existence of catalyst carrier is generally not easy to remove, resulting in high ash content, whisker carbon nanotubes adopt floating gas phase catalysis method, no need to separately prepare solid catalyst, short synthesis process cycle, the process is relatively simple. The purification process is high temperature purification with low ash content. Carbon nanoparticles are prepared by top-down method.
