However, the complications of the fabrication methods impede the widespread usages of newly developed materials even with the superior properties in many cases. Here, we demonstrate the feasibility of a highly-efficient and potentially-continuous fiber-spinning method to produce high-performance carbon nanotube (CNT) fiber (CNTF). The processing time is <1 min from synthesis of CNTs to fabrication of highly densified and aligned CNTFs. CNTFs that are fabricated by the developed spinning method are ultra-lightweight, strong (specific tensile strength = 4.08 +/- 0.25 Ntex(-1)), stiff (specific tensile modulus =187.5 +/- 7.4 Ntex(-1)), electrically conductive (2,270 S m(2)kg(-1)), and highly flexible (knot efficiency = 48 +/- 15%), so they are suitable for various high-value fabric-based applications.
