▎ 摘　　要

NOVELTY - Preparing graphene fiber comprises (i) checking the operation of the device before starting the device to prepare graphene fiber; (ii) manually adding graphene raw materials into the hopper; (iii) starting the motor when the graphene material is added, stirring and mixing graphene raw material and fiber slurry inside the stirring barrel by stirring rod; (iii) using vibrating mechanism to make the stirring barrel vibrate up and down while stirring the fiber slurry; and (iv) forming the mixed slurry into filaments and cooling to shape, where the graphene fiber can be prepared by the subsequent high temperature or chemical agent reduction. USE - The method is useful for preparing graphene fiber. ADVANTAGE - The method is improves the molding quality of graphene fibers. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for preparing graphene fiber (Drawing includes non-English language text).
