Carbon nanofibers (CNF) have a wide range of applications and my country’s research efforts are increasing

Carbon nanofiber (CNF) refers to a fibrous nanocarbon material made of rolled multi-layer graphite sheets with a diameter of 10~500nm and a length of 0.5~100μm. Carbon nanofibers have the characteristics of good electrical conductivity, good thermal conductivity, high strength, lightweight, strong adsorption performance, and large specific surface area. They are widely used in catalysts, water treatment, sensors, batteries and other fields.

Carbon nanofiber preparation methods include biological preparation methods, solid-phase synthesis methods, chemical vapor deposition methods, template methods, and electrospinning methods. Electrospinning refers to converting polymer solution or melt into carbon nanofibers in an electrostatic field. Compared with other preparation methods, electrospinning has the advantages of high production efficiency, wide source of raw materials, and low production cost, and is the mainstream preparation method of carbon nanofibers.

In recent years, Chinese enterprises and scientific research institutions have continued to increase their research efforts on carbon nanofibers and have made many new developments. In 2022, the team of Professor Li Congju of the University of Science and Technology Beijing successfully prepared macroporous interconnected hollow carbon nanofibers using the coaxial electrospinning method. With in-depth research and technological advancement, the development speed of my country’s carbon nanofiber industry will further accelerate.

According to the “2023-2028 Carbon Nanofiber (CNF) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center 》 shows that carbon nanofiber is a one-dimensional nanofiber between carbon nanotubes and carbon fibers. It has the excellent properties of carbon nanotubes and carbon fibers and has a wide range of applications, including catalysts, water treatment, sensors, and batteries. wait. In the field of sensors, carbon nanofibers have electrocatalytic activity and can be used to manufacture electrochemical sensors; in the field of batteries, carbon nanofibers can be used as anode materials for lithium-ion batteries, which can effectively improve battery cycle life and charge and discharge performance.

Major players in the global carbon nanofiber market include Taiwan’s APPLIED SCIENCES, US NanoAmor, Japan’s Showa Denko, Spain’s Grupo Antolin, etc. Antolin is the world’s largest automotive interior manufacturer, and the company is currently vigorously promoting research on carbon nanofibers for hydrogen fuel cells.

my country’s carbon nanofiber industry started late. Due to factors such as high technical barriers, there are no companies with large-scale production capabilities in my country, and the industry is in the laboratory research and development stage. The main research units on carbon nanofibers in my country include University of Science and Technology Beijing, Tsinghua University, University of Science and Technology of China, Chinese Academy of Sciences, etc.

Industry analysts said that carbon nanofibers, as one-dimensional nanofibers, have excellent performance and have broad applications in popular fields such as sensors and batteries. Prospects: As the research intensity of my country’s scientific research institutions continues to increase, its application scope will be further expanded. At present, my country’s carbon nanofiber industry is in the laboratory research and development stage and has not yet achieved commercial application. In the future, driven by technological innovation, the development speed of my country’s carbon nanofiber industry will further accelerate.
