Relationship between polymer-CNT affinity and properties of polymer infiltrated carbon nanotube yarns

Polymers which have different affinity with carbon nanotube (CNT) were infiltrated into carbon nanotube yarns (CNTYs) to improve mechanical and electrical properties. Those properties were highly related with the internal structure and the affinity of CNT-polymer. Polymer with the poorest affinity toward CNTs showed the greatest advancement in the mechanical and electrical properties of the CNTYs among three different polymers. Deformation behavior of CNTY at each stage of stress-strain curves could be defined based on the structure and properties of polymer infiltrated CNTYs.
