Title:
GRAPHENE COMPOSITE FIBER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/107978
Kind Code:
A1
Abstract:
A graphene composite fiber and a manufacturing method therefor are disclosed. A graphene composite fiber manufacturing method of the present invention comprises: a first solution preparation step of preparing a first solution by dispersing graphene in a dispersion solvent; a second solution preparation step of preparing a second solution by adding a polymer to the first solution; a graphene master chip preparation step of solidifying the second solution, and then cutting same to prepare a plurality of graphene master chips; and a graphene composite fiber preparation step of preparing a graphene composite fiber by spinning the plurality of graphene master chips and a polymer by means of a fiber spinning device.
