摘　　要：Owing to the intrinsic excellent mechanical,electrical,and thermal properties of carbon nanotubes(CNTs),carbon nanotube fibers(CNTFs)have been expected to become promising candidates for the next-generation of high-performance fibers.They have received considerable interest for cutting-edge applications,such as ultra-light electric wire,aerospace craft,military equipment,and space elevators.Wet-spinning is a broadly utilized commercial technique for high-performance fiber manufacturing.Thus,compared with array spinning from drawable CNTs vertical array and direct dry spinning from floating catalyst chemical vapor deposition(FCCVD),the wet-spinning technique is considered to be a promising strategy to realize the production of CNTFs on a large scale.In this tutorial review,we begin with a summative description of CNTFs wet-spinning process.Then,we discuss the high-concentration CNTs wet-spinning dope preparation strategies and corresponding non-covalent adsorption/charge transfer mechanisms.The filament solidification during the coagulation process is another critical procedure for determining the configurations and properties for derived CNTFs.Next,we discuss post-treatment,including continuous drafting and thermal annealing,to further optimize the CNTs orientation and compact configuration.Finally,we summarize the physical property-structure relationship to give insights for further performance promotion in order to satisfy the prerequisite for detailed application.Insights into propelling high-performance CNTFs production from lab-scale to industry-scale are proposed,in anticipation of this novel fiber having an impact on our lives in the near future.
