Graphene is the thinnest, most powerful, and most conductive and thermally conductive new nanocarbon material discovered so far. Graphene is called "black gold" and is the "king of new materials". scientists even predict that graphene will "completely change the 21st century."
Most companies have different losses in the graphene industry. After years of market struggle, the domestic carbon nanotube industry has basically no government support, but most of them are profitable, with large companies making profits of over 100 million and small companies making profits of over 100 million. After so many years of iteration and changes in the new materials industry, the hot topics and waves of the times have finally been initially industrialized.
After more than ten years of research and development and promotion, carbon nanotubes as conductive agents are very obvious in the lithium battery industry and their use has become more and more popular. In addition to power batteries, carbon nanotube conductive agents have also begun to be used in digital batteries. The amount of carbon nanotube conductive agent added to is greatly reduced than the traditional carbon black conductive agent, and at the same time, the amount of adhesive can be reduced to about 50%, which has comprehensive and obvious benefits for lithium-ion battery .

As the application scale of new technologies such as high-nickel positive electrode, silicon-based negative electrode and solid-state battery expands, the application of carbon nanotubes will explode, and in the field of lithium batteries alone, it will become a market of tens of billions of dollars every year.
carbon nanotubes will have a broader market in touch screens, transistors, , biomedicine, solar photovoltaic cells, tires, fuel cell , drug delivery, hydrogen storage, polymer materials, capacitor , composite materials, etc., and will continue to break through multiple markets of tens of billions and become an industry with a market of hundreds of billions of dollars.
Thermoplastic polyurethane (TPU) has been widely used in electronics, automobiles, medicine and other fields due to its high mechanical strength, good processing performance and excellent biocompatible performance. Flush blending of TPU with conductive carbon black, graphene or carbon nanotubes, etc. can prepare composite materials with conductive properties.
What is carbon nanotube?
carbon nanotubes (CNTs), also known as Bucky tube , is a one-dimensional quantum material with a special structure (radial dimensions are the order of nanometers, axial dimensions are the order of micrometers, and both ends of the tube are basically sealed).
Carbon nanotubes mainly consist of carbon atoms arranged in hexagonally to coaxial circular tubes with several layers to dozens of layers. The layer is maintained at a fixed distance of about 0.34 nm and the diameter is generally 2~20 nm.
carbon nanotubes are lightweight and have perfect connections in hexagonal structures, with many abnormal mechanical, electrical and chemical properties.
In recent years, with the deepening of carbon nanotubes and nanomaterial research, its broad application prospects have been continuously revealed, and are one of the research hotspots in the field of materials science.
TPU/carbon nanotube blended composite materials in the aviation field
Aviation tire is the only component that comes into contact with the ground during take-off and landing of the aircraft. It has always been regarded as the "jewel in the crown" of the tire manufacturing industry.
Add TPU/carbon nanotube blended composite material to the aviation tire tread glue to make it have the advantages of anti-static, high thermal conductivity, high wear resistance, and high tear resistance to improve the comprehensive performance of the tire and enable the static charge generated by the tire during takeoff and landing to evenly transmit to the ground. It is easier to save manufacturing costs.
Use carbon nanometers to blend with polymer materials to obtain new composite materials such as excellent mechanical properties, good conductivity, corrosion resistance and electromagnetic shielding.Carbon nanotube polymer composite materials are considered to be a substitute for the traditional smart material , and their application scope will become more and more extensive in the future.
