▎ 摘　　要

NOVELTY - Manufacturing graphene-based fiber involves preparing a graphene-based dispersion containing a graphene-based material, and obtaining flat fibers by wet spinning graphene-based dispersion liquid with a flat nozzle having a cross-section having different lengths of long axis and the short axis of the aspect ratio in a coagulating solution, and then drying it to obtain final product. USE - Method for manufacturing graphene-based fiber. ADVANTAGE - The method enables to manufacture graphene-based fiber, which has excellent mechanical, thermal and electrical property, excellent alignment and orientation in fiber axis direction and maintains liquid crystal structure, and reduces defect such as pores and wrinkles in graphene-based fiber.
