| Outline of Final Research Achievements |
Research efforts have been carried out to fabricate macroscopic yarn structure from super-long forest of vertically aligned carbon nanotubes (CNTs) to make the use of the CNTs unique properties. In this perspective research, the rapid synthesis of CNT forest, production of CNT yarns from a CNT forest, and mechanical and electrical properties of CNT yarns are extensively investigated and reported in detail. Hence, the first efforts were concentrated to study and optimize the parameters such as precursor feed, temperature, catalyst configuration, time as well as the interlinks of CNT bundles, number of walls and length of the individual CNT in the forest, which is appropriate for the spinning of a continuous very few walls of CNT yarn. And, the post process of CNT yarn by bias treatment by applying high voltage was considered as possible ways to improve both the mechanical and electrical properties.
