background
● CNT has ultra-high strength and larger current capacity than metal
● CNT yarn enables CNTs to be used in a macro scale
● Properties of CNT yarns are inferior to that of CNT itself
● CNT yarn enables CNTs to be used in a macro scale
● Properties of CNT yarns are inferior to that of CNT itself
summary
● Untwisted CNT yarns were fabricated from CNT array (Fig. 1)
● Impurities and defect structures were removed by graphitization treatment
● CNT yarns were combined with polymer or metal to enhance load transfer capability or conductivity between CNTs
