▎ 摘 要
NOVELTY - Graphene liquid crystal fiber comprises graphene liquid crystal fibers having surface folds formed to have a fiber roundness and transition metal catalyst layers coated on the graphene liquid crystal fibers. USE - Graphene liquid crystal fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing graphene liquid crystal fiber, which involves: (A) spinning a graphene oxide spinning solution to obtain a spinning fiber; and (B) preparing a graphene liquid crystal fiber including a transition metal catalyst and reducing surface roughness to have a fiber roundness, where the grafted liquid crystal fiber-transition metal-based catalyst fiber composite comprises a graphene liquid crystal fiber-transition metal-based catalyst fiber composite.
