▎ 摘　　要

NOVELTY - The preparation method of graphene-based hollow fiber involves preparing graphene-based material solution, coating the solution on a selected heat-shrinkable polymer fiber to obtain core-shell structure composite fiber, heating the composite fiber so that the shell layer of the graphene-based material layer is separated from the core layer of polymer fiber layer because of different heat-shrinkable capability, and extracting the shrinkage the polymer fiber. USE - Preparation method of graphene-based hollow fiber (claimed). ADVANTAGE - The method enables preparation of graphene-based hollow fiber by environmentally-friendly process.
