摘要： A graphene ribbon fiber manufacturing process, where a coagulation medium flows in the same direction as the graphene ribbon fibers. The process for spinning graphene ribbon fibers starts with unzipping carbon nanotubes to form graphene ribbons, purifying and drying the graphene ribbons and subsequent dissolving of the graphene ribbons in a suitable solvent, preferably a super acid to form a spin-dope. The spin-dope is spun such that the accrued fibers are guided into a coagulation medium, also known as anti-solvent, where the spun or accrued fibers are coagulated. The coagulated graphene ribbon fibers are stripped, neutralized and washed and wound on bobbins.

摘要： Carbon nanotubes (CNT) fibers having a resistivity lower than 120 μΩ*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 μm. The carbon nanotubes fibers can further have a resistivity lower than 50 μΩ*cm. At the same time, the CNT fibers can have high modulus.
