Recently, CSIRO has developed a modified dry spinning process for converting CNT forests into yarn in whichudthe CNT structure is more aligned and the mechanical properties of yarns are improved.The partitioning of theudspinning system into separate zones has enabled further development of other types of CNT based products. Usingudthis modified system, a CNT polymer composite yarn manufacturing process was set up with simple control of theudalignment and tension of the CNT-based reinforcing structure. In contrast to previous methods where the CNTs are dispersed in polymer solution, in this work, the polymer filled the pores between the stretched and aligned CNT web/sliver and formed a unique CNT-polymer composite. The aim of this work was to demonstrate a differentudapproach for producing the CNT-based polymer composite yarns with properties that may satisfy many differentudengineering specifications, including biomedical device applications.
