▎ 摘　　要

NOVELTY - Preparation of graphene fiber with controllable twist involves conveying a graphene oxide spinning solution from upper portion of spinning shaft to the spinning shaft at a predetermined speed, solidifying the spinning solution, drawing and twisting with hot air from top to bottom to obtain graphene oxide fiber, and chemically reducing. The twisting collection device is provided below the spinning shaft, and the drawn fiber is twisted with different twists by controlling the rotation of the twisting collection device. USE - Preparation of graphene fiber with controllable twist. ADVANTAGE - The graphene fiber with controlled and adjustable structure, excellent mechanical properties and electrochemical performance can be produced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing device of graphene fiber.
