GRAPHENE FIBER AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2012/124934

A2

The present invention relates to a method for manufacturing a graphene fiber and a graphene fiber manufactured thereby, comprising the following steps: a) preparing a dispersion liquid by dispersing graphene with a surfactant in a solvent; b) preparing a composite fiber by mixing the dispersion liquid with a polymer solution, wet spinning and drying same; and c) removing polymers by heat-treating or treating the composite fiber with strong acid. The graphene fiber manufactured by the method has superior electric and mechanical properties, is flexible, and can be utilized as a storage medium for energy, hydrogen, etc. due to porosity from having a wrinkled structure.
