Abstract
Highly Strong and Conductive Acid-spun Carbon Nanotube Fibers Bon-Cheol Ku (E-mail: cnt@kist.re.kr) Although carbon nanotubes(CNTs) have outstanding properties, CNT fibers (CNTFs) have not yet reached that level [1]. To enhance mechanical and electrical properties of CNTFs, a few parameters including CNT length, aspect ratio, alignment, densification, and cross-linking should be considered and optimized [2,3]. One promising approach to enhance mechanical and electrical properties may be wet spinning and liquid crystalline spinning method using super acid [4]. Herein, I will present an effective way to make highly strong and conductive CNTFs. References 1.
