| Outline of Final Research Achievements |
I researched on three themes;"1. Experiment of formation of high conductivity DWCNT wire (high purity and selective long DWCNT by FCCVD method)" "2. High conductivity of CNT-yarn" "3. Mechanism elucidation".
In the synthesis, I proceeded with reproducibility of sample production. At the same time, studies on secondary treatment were conducted, but the resistivity of the CNT-yarn was on the order of 1 × 10-5 Ω*cm. The structure confirmation by Raman spectroscopy and XPS were carried out, and the CNTs before and after the secondary treatment were evaluated. However, the cause of the improvement in electrical conductivity has not been clearly confirmed.
At the conference, related parties were interested in my research contents. With incorporating new perspectives, I am continuing our connection. I will investigate the factor identification with the electrical characteristics of the CNT-yarn and continue research.
