Macroscopic, Neat, Single-Walled Carbon Nanotube Fibers

Well-aligned macroscopic fibers composed solely of single-walled carbon nano-tubes (SWNTs) were produced by conventional spinning. Fuming sulfuric acid charges SWNTs and promotes their ordering into an aligned phase of individual mobile SWNTs surrounded by acid anions. This ordered dispersion was ex...

Zusammenfassung:Well-aligned macroscopic fibers composed solely of single-walled carbon nano-tubes (SWNTs) were produced by conventional spinning. Fuming sulfuric acid charges SWNTs and promotes their ordering into an aligned phase of individual mobile SWNTs surrounded by acid anions. This ordered dispersion was extruded via solution spinning into continuous lengths of macroscopic neat SWNT fibers. Such fibers possess interesting structural composition and physical properties.
