Title:
PROCESS FOR SPINNING GRAPHENE RIBBON FIBERS
Document Type and Number:
WIPO Patent Application WO/2011/134717
Kind Code:
A1
Abstract:
The invention pertains to a graphene ribbon fiber manufacturing process wherein 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.
