The article discusses the wet-spinning of carbon nanotube (CNT) fibers, focusing on dispersion, processing, and properties. It highlights the importance of wet-spinning as a promising method for large-scale production of CNT fibers, which are expected to be key materials for next-generation high-performance fibers. The review covers the preparation of high-concentration CNT wet-spinning dope, non-covalent adsorption/charge transfer mechanisms, filament solidification during coagulation, post-treatment processes, and the physical property-structure relationship. It also discusses the development history of wet-spinning CNT fibers, the basic wet-spinning process, and the preparation strategies for spinning dopes. The review emphasizes the role of non-covalent adsorption and charge transfer in achieving high-quality CNT fibers, as well as the impact of coagulation parameters on the final properties of CNT fibers. The article concludes that the wet-spinning process, combined with post-treatment, can produce high-performance CNT fibers with excellent mechanical, electrical, and thermal properties.The article discusses the wet-spinning of carbon nanotube (CNT) fibers, focusing on dispersion, processing, and properties.
