Resumen
A high-speed incandescent tension annealing process (ITAP) is used to increase the modulus and strength of twist-spun carbon nanotube yarns by up to 12-fold and 2.6-fold, respectively, provide remarkable resistance to oxidation and powerful protonating acids, and freeze yarn untwist. This twist stability enables torsional artificial-muscle motors having improved performance and minimizes problematic untwist during weaving nanotube yarns. 28 31 6598 6605 Air Force Office of Scientific Research [FA9550-12-1-0035, FA9550-12-1-0211, FA2386-13-1-4119] Robert A.
