PROBLEM TO BE SOLVED: To provide a nanofiber yarn, ribbon and sheet; to provide methods for producing the yarn, ribbon and sheet; and to provide applications of the yarn, ribbon and sheet.SOLUTION: In some embodiments, a nanotube yarn, ribbon and sheet comprise carbon nanotubes. Specifically, such carbon nanotubes of the present invention provide the following unique properties and property combinations, for example: extreme toughness; resistance to failure at a knot; high levels of electrical and thermal conductivities; high absorption of energy that occurs reversibly; up to 13% strain-to-failure as compared with a few percent in other fibers with similar toughness; very high resistance to creep; retention of strength even when heated in air at 450°C for one hour; and very high radiation resistance and UV resistance even when irradiated in air.SELECTED DRAWING: None |
