Title:
PREPARATION METHOD FOR GRAPHENE FIBER
Document Type and Number:
WIPO Patent Application WO/2021/102932
Kind Code:
A1
Abstract:
Disclosed in the present invention is a preparation method for a graphene fiber. The graphene fiber has excellent performances, i.e., high thermal conductivity, high electric conductivity, high strength, and high modulus. The method comprises: spinning a liquid-crystal spinning solution of graphene oxide by means of a spinneret hole in a coagulation bath, performing plastic stretching in a plastic stretching bath to reach an optimal stretch ratio, and performing chemical reduction and thermal treatment to obtain a high-performance graphene fiber.
