Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for spinning graphene ribbons into fibers comprising the steps of: supplying a spin-dope comprising graphene ribbons to a spinneret, spinning the spin-dope into accrued graphene ribbon fibers, coagulating the accrued graphene ribbon fibers in a coagulation medium to form coagulated graphene ribbon fibers, mechanically stripping, optionally neutralizing and washing the coagulated graphene ribbon fibers, and winding the coagulated graph…
