Title:
GRAPHENE FIBER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/179900
Kind Code:
A1
Abstract:
Provided is a method for manufacturing graphene fiber comprising the steps of: preparing a source solution comprising graphene oxides; spinning the source solution with a base solution comprising heterogeneous elements to produce oxidized graphene fiber; separating, washing and drying the graphene fiber from the base solution to obtain the oxidized graphene fiber comprising the heterogeneous elements; and subjecting the dried oxidized graphene fiber comprising the heterogeneous elements to thermal treatment to produce graphene fiber doped with the heterogeneous elements, wherein the elongation percentage of the graphene fiber is controlled according to the concentration and the spinning speed of the source solution.
