Description
Summary:Macroscopic carbon nanotube (CNT) fibers approximately 1 mm in diameter and 6 m long were prepared from CNT socks. The as-prepared macro-fiber exhibited excellent flexibility and manipulability. Microscopic examination showed that the fibers mainly consisted of CNTs with a fine graphitic structure and a large diameter (approximately 4.6 nm to 6.3 nm). Electric arcs were generated when the macro-fiber came in contact with a metallic electrode at a voltage as low as 30 V. These arcs had high intensity, and the generated temperature was sufficiently high such that the metallic anode electrode (stannum or copper wire) easily melted. CNT crystallinity was only slightly damaged after the electric circuit was discharged. The high intensity of the generated electric arcs suggested the potential applications of the macro-fiber in welding, melting metals, or other related fields.
