Forming graphene-based continuous or long fiber from chemically functionalized graphene sheets involves e.g. making graphene dispersion of the sheets dispersed in liquid medium and dispensing and depositing onto supporting substrate.

ZHAMU A, JANG B Z

Graphene-based long fibers for forming fiber yarn or bundle, comprise graphene sheets which are chemically bonded or interconnected with one another having preset inter-planar spacing, non-carbon element content, length and physical density.

ZHAMU A, JANG B Z

Fabricating high-performance carbon fiber, comprises making graphene carbon fiber composition by mixing composition including one of e.g. rayon-based carbon fiber to fabricate carbon fiber and graphene powder, and heating composition.

LEE J K, CHOI W K

Manufacture of carbon fibers used in graphene sheets and high-tech composites, involves using precursor comprising carbon black modified with at least one cyclic compound promoter.

KEMP R A, TAHA M R

Graphene carbon fiber composition for fabricating high-performance carbon fiber comprises a composition for fabricating carbon fiber; and graphene powder.

LEE J K, CHOI W K

Graphene oxide sheet used for graphene-containing material, is obtained by dispersing graphene-containing carbon substance using dispersing agent to reduce size of aggregation unit of carbon substance, and oxidizing resulting product.
