▎ 摘　　要

NOVELTY - Preparing graphene-based hollow fiber involves selecting graphite alkene material solution, raw material and one-dimensional material template. The raw material is fixed on the surface of the one-dimensional material template to obtain composite one-dimensional material template. The obtained composite one-dimensional material template surface is coated with graphene-based material solution to obtain graphene material. The obtained graphene material is placed under changed environment with volume-shrinkable state and separated from the graphene-based material layer. USE - Method for preparing graphene-based hollow fiber (claimed). ADVANTAGE - The method enables to prepare graphene-based hollow fiber in a convenient, cost-effective, and eco-friendly manner, which has high efficiency. DETAILED DESCRIPTION - Preparing graphene-based hollow fiber involves selecting graphite alkene material solution, raw material and one-dimensional material template. The raw material is fixed on the surface of the one-dimensional material template to obtain composite one-dimensional material template. The obtained composite one-dimensional material template surface is coated with graphene-based material solution to obtain graphene material. The obtained graphene material is placed under changed environment with volume-shrinkable state and separated from the graphene-based material layer. The one-dimensional material template is then taken away or the graphene-based material shell is taken out to obtain the desired graphene-based hollow fibers.
