Abstract

Recently, CSIRO has developed a modified dry spinning process for converting CNT forests into yarn in which the CNT structure is more aligned and the mechanical properties of yarns are improved.The partitioning of the spinning system into separate zones has enabled further development of other types of CNT based products. Using this modified system, a CNT polymer composite yarn manufacturing process was set up with simple control of the alignment 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 different approach for producing the CNT-based polymer composite yarns with properties that may satisfy many different engineering specifications, including biomedical device applications.
