摘要	Carbon nanotube fibers (CNTFs) are considered an ideal candidate as next-generation conducting wires due to their high conductivity and low density. However, the orientation and compaction of the nanotubes in a CNTF need to be further improved to achieve even higher conductivity and ampacity. Here the fabrication of double-wall CNTFs (DWCNTFs) is reported by a dry-jet wet spinning method, which significantly improves the orientation and compaction of the carbon nanotubes (CNTs). As a result, the obtained DWCNTFs have a record high electrical conductivity of 1.1 x 107 S m-1 and ampacity of 8.0 x 108 A m-2. The fibers also have a high tensile strength of 1.65 GPa and a toughness of 130.9 MJ m-3, among the highest for wet-spun CNTFs. The DWCNTFs preserve their integrity and conductivity after more than 5000 bending cycles. Theoretical calculations indicate that in a dry-jet wet-spinning process, gravity promotes the orientation of the CNTs along the axial direction of the fiber. Carbon nanotube (CNT) fibers composed of numerous highly-oriented, densely-packed double-wall CNTs are prepared by a dry-jet wet spinning method, which shows a record high electrical conductivity of 1.1 x 107 S m-1 and ampacity of 8.0 x 108 A m-2, as well as a high tensile strength of 1.65 GPa and a toughness of 130.9 MJ m-3. image
