Abstract
Recent studies regarding the properties of carbon nanotubes (CNT) have made remarkable progress in CNT fibers research. However no CNT fibers showed the properties of CNTs because CNTs in fibers have weak interfacial bonding with low shear modulus in the pristine form. Thus, it is upmost interest to develop and employ post-production treatments to the CNT fibers that would potentially improve their properties. In this study, post-treatments resulted in improvement of strength of CNT fibers up to 40%.
