| Outline of Final Research Achievements |
The aim of this study is to fabricate innovative high strength CNT yarns in which excellent mechanical properties of CNTs are fully demonstrated. Untwisted CNT yarns were fabricated by dry spinning method using a ceramics die. Strengthening constituent CNTs of the CNT yarn and improvement of the load transmission efficiency between the CNTs were revealed to be necessary for development of high strength CNT yarns by strength evaluation of a CNT and molecular dynamics method. Untwisted CNT yarns were purified by graphitization treatment and combined with polymers such as PVA and PAN, and their strength reached 2.4 GPa.
