Outline of Final Research Achievements

Carbon nanotube (CNT) yarns have attracted much attention because of those potential applications for various fields such as structural materials, multifunctional fabrics, and cables. Although various methods for formation of CNT yarns have been developed, these methods have drawbacks such as its complicated process, limitation of CNTs used for the spinning, and so on. This study aimed to develop a new method for spinning of CNTs that enables high efficiency CNT spinning using any kind of CNTs with which the formation of yarns was difficult by the conventional CNT spinning method. Here we used a CNT filament formation phenomenon induced by a gas discharge breakdown, which we found for the first time. We successfully fabricated a CNT yarn using this method and confirmed that formation of CNT yarns are possible using various kind of CNTs such as multiwall and single wall CNTs.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により，CNT紡績が従来方法よりも容易にかつ高効率に実施することが可能となる。さらに，従来の方法では実施が困難であったタイプのCNTでも紡績が実施可能となる。これにより，従来よりも作製するCNT撚糸への機能付与がより容易になり，さらに作成時のコストダウンが実現可能となる。CNT撚糸は軽量でかつ高強度のケーブルとして，あるいは紡織布として利用可能であり，様々な工業製品の構造材料として展開可能である。
