METHOD OF SPINNING FIBRES FROM GRAPHENE RIBBONS Russian patent published in 2015 - IPC D01F9/12 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical fibre technology and a method of spinning fibres from graphene ribbons. The method of spinning fibres from graphene ribbons begins with unfolding carbon nanotubes to form graphene ribbons, cleaning and drying the graphene ribbons and dissolving the graphene ribbons in a suitable solvent, preferably a superacid, to form a spinning solution. The spinning solution is used to spin such that spliced fibres are fed into a coagulation medium, also known as an anti-solvent, where spun or spliced fibres undergo coagulation. The coagulation medium flows in the same direction as the orientation of fibres formed from the graphene ribbons. The coagulated fibres, formed from the graphene ribbons, are pulled off, neutralised and washed and then wound on a spool.

EFFECT: invention enables to produce fibres from graphene ribbons.
