Recently, with the special support of the Beijing Science and Technology Commission Nanotechnology, Tsinghua University has successfully developed high-performance carbon nanotube wires, and has carried out research on the application of brain pacemaker electrodes and carbon nanotube wire prototype DC motors.
Carbon nanotubes have the characteristics of light weight, high strength, excellent electrical and thermal conductivity, and are expected to replace traditional metal wires in aerospace, biomedical and other fields. Conventional carbon nanotube preparation methods will result in the mixing of metal nanotubes and semiconductor nanotubes, of which the semiconductor properties account for about 2/3, resulting in the carbon nanotube wire conductivity is two orders of magnitude lower than copper wire, seriously restricting the carbon nanotube wire Practical application.
The entire team of Tsinghua University Wei Jin adopted the method of controlling process parameters to increase the metallicity ratio of carbon nanotube wires to 1/2, to achieve the rapid and continuous growth of high-quality carbon nanotube films and filaments, and to prepare the same conductivity as copper wires Grade high-performance carbon nanotube wire, and the mechanical strength of the wire is 3-4 times higher than copper. The team also conducted a carbon nanotube wire brain pacemaker electrode application study, the results show that the electrode heat generated in the nuclear magnetic environment reduced by 90%; at the same time prepared a carbon nanotube wire-based prototype DC motor, for reducing aerospace load Has an important role.
