Scientists have discovered that new carbon nanofibers have the same high conductivity as metals

Scientists discovered carbon nanotubes (CNTs) in 1991. Compared with common conductive materials, their electrical conductivity is much better than that of the latter. When their weight is 1/6 of the general conductive material, their electrical conductivity can be achieved. About 100 times the general conductive material. However, it is not easy to apply this CNT to practice. Recently, researchers have discovered a brand new CNT fiber that not only has the ability to conduct heat and electricity like a metal wire, but also achieves the same strength as a normal carbon tube and has the same flexibility as a textile fiber. Sex.

This research team consisting of Rice University, Teijin Aramid of the Netherlands, and the United States Air Force Laboratory and the Israel Institute of Technology spent 10 years to complete this research task. It is reported that the team used a wet spinning forming chemical process to dissolve carbon nanotube raw materials into liquids through chlorosulfonic acid, and then formed them into long chains. Researchers say that this carbon nanotube is the best CNT fiber they have developed so far.

Matteo Pasquali, the head of the research, pointed out that the carbon nanofibers they discovered this time have equivalent electrical conductivity to copper, gold and aluminum telecommunications, and its strength is greater than that of the carbon nanofibers. It also means that This material not only has a special metal, but also overcomes the disadvantages of metal conductors.
