摘　　要：Carbon nanotubes(CNTs)have received considerable attention for their excellent thermal and electrical conductivity as well as scalable production.However,CNT dispersions are prone to settling and have a short shelf time,especially under high concentration,which significantly hinders their further processing and increases transportation costs.Here,we report a highly concentrated CNT dough enabled by ionic liquid crystal(ILC)as auxiliaries.Benefiting from the temperature-controlled physical transformation of the ILC,the CNTs of the powder state are successfully transferred to highly processable dough with excellent electrical conductivity,flame retardancy,and outstanding redispersibility even after 180 days of storage.In particular,the CNT dough exhibits excellent self-healing properties and good reshapable capability.Various bulk form CNT derived from the ILC armored CNT dough are realized by facile processing technique.Hybrid nanocomposite papers with ANF nanofiber exhibited excellent photothermal conversion and Joule heating properties.The redispersible CNT doughs presented here promise to revolutionize traditional CNT powder and dispersions as the primary raw material for building CNT-based architectures and facilitate the large-scale application of CNTs.
