Carbon nanotubes(CNTs) are widely used in many applications in nanotechnology, electronics, optics, and other fields of materials science due to its remarkable properties. Fabrication of CNT fibers is an important challenge so that CNT fibers are to be handled easily and utilized in much wider range fields. In the last few years, researchers have designed a few methods to convert CNT powder into continuous fibers. Of them, representative methods are ‘Coagulation method’, ‘Spinning from a nanotube mat’ and 'Direct growth of CNT fiber' etc. In this study, we fabricated CNT fibers continuously from chemical vapor deposition(CVD) synthesis and investigated the effects of processing parameters on the CNT fibers. The CNT fibers were composed of more than 95wt% CNTs. Also, we extremely enhanced CNT fibers' mechanical, electrical and starch-resistance properties through post-processing such as solvent shrinking and polymer coating. |
