Multi Walled Carbon Nanotubes Description
Use natural gas, ethylene and other carbon sources to mass-produce general-purpose multi walled carbon nanotubes with various outer diameters and lengths, and carry out functional treatments such as hydroxylation and carboxylation on them. This type of product is easy to disperse, has excellent electrical and thermal conductivity and enhanced performance. Mainly used in lithium-ion battery conductive additives, conductive materials, heat conduction and heat dissipation materials, reinforcing materials, catalyst carriers and other fields.
We also have reagent-grade high-purity multi walled carbon nanotubes (TNM0). Compared with industrial grades, they have smaller diameters, larger specific surface areas, and lower metal impurities. They can be used in scientific research or as conductive additives for lithium-ion batteries.

Application prospect of carbon nanomaterials
Carbon nanomaterials have the characteristics of good stability, high strength, high specific surface area, and abundant sources. They are new nanomaterials with the greatest development potential. At present, the nano-carbon materials that have obtained large-scale and mature applications are mainly carbon nanotubes, which are used in lithium-ion battery conductive agents, flexible transparent conductive film materials, coating heat dissipation functional bodies, polymer composite materials, electromagnetic shielding materials, etc. For example, carbon nanotubes have been applied in kilotons in the lithium-ion battery conductive agent industry. It is estimated that by 2025, the demand for conductive agents will exceed 600,000 tons, and the demand for carbon nanotube powder will be about 30,000 tons.
