▎ 摘　　要

NOVELTY - The method involves preparing (S110) a mixed solution of graphene oxide and polyurethane. A gel fiber made of graphene oxide and polyurethane is prepared (S120) by using the mixed solution in a wet spinning method. The gel fibers are reduced (S130) to form reduced graphene oxide and polyurethane fibers. The reduced graphene oxide and polyurethane fibers are stretched (S140). The surface is treated (S150) using plasma while the reduced graphene oxide and polyurethane fibers are stretched. The metal nanoparticles are deposited (S160) on the reduced graphene oxide and polyurethane fibers. The stretched state of the reduced graphene oxide and polyurethane fibers are released (S170) to form a wrinkled shape. USE - Method for manufacturing elastic hybrid fiber (claimed). ADVANTAGE - The stretchable nano-wrinkled hybrid fiber has a high degree of reactivity that replace enzymes and at the same time has elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an elastic hybrid fiber. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the manufacturing of an elastic hybrid fiber.
