FIELD: chemistry.
SUBSTANCE: fibers are prepared by wet spinning, comprising the steps of feeding a spinning solution containing carbon nanotubes to a spinneret, spinning solution extruding through at least one spinning orifice in the spinneret to form the spun carbon nanotube fibers, spun carbon nanotube fibers coagulating in a coagulation medium to form coagulated carbon nanotube fibers, where the carbon nanotube fibers are drawn with a draw ratio greater than 1.0, and where the carbon nanotubes have a length of at least 0.5 microns.
EFFECT: invention provides carbon nanotube fibers with a resistance below 120 microO⋅cm, high elasticity modulus.
