  • CARBON NANOTUBES FIBER HAVING LOW RESISTIVITY, HIGH MODULUS AND/OR HIGH THERMAL CONDUCTIVITY AND A METHOD OF PREPARING SUCH FIBERS BY SPINNING USING A FIBER SPIN-DOPE
    Publication number: 20140363669
    Abstract: Carbon nanotubes (CNT) fibers having a resistivity lower than 120 ??*cm are prepared by a wet spinning process including the steps of supplying a spin-dope of carbon nanotubes to a spinneret, extruding the spin-dope through at least one spinning hole in the spinneret to form spun carbon nanotubes fibers, and coagulating the spun carbon nanotubes fibers in a coagulation medium to form coagulated carbon nanotubes fibers. The carbon nanotubes fibers are drawn at a draw ratio higher than 1.0. The carbon nanotubes have a length of at least 0.5 ?m. The carbon nanotubes fibers can further have a resistivity lower than 50 ??*cm. At the same time, the CNT fibers can have high modulus.
