Effect of graphitization on mechanical properties of untwisted carbon nanotube yarn and its strength development mechanism

Nihon Kikai Gakkai ronbunshu, 2018
Carbon nanotube yarn, which is an aggregation of Carbon nanotubes (CNTs), enables CNTs to be used on macro scale. However, tensile strength of the CNT yarn is much lower than CNT itself, and improvement of the mechanical properties is a challenge for ...
