▎ 摘　　要

NOVELTY - Flexible self-supporting metal-organic framework-graphene oxide film comprises zeolitic imidazolate framework-8 nanocrystal or zeolitic imidazolate framework/graphene oxide nanosheet and graphene oxide, and bacterial cellulose. Product is obtained by vacuum filtering. USE - The flexible self-supporting metal-organic framework-graphene oxide film is used in ion separation and dye removal. ADVANTAGE - The film has controllable ZIF-8 crystal size, flexible self-supporting feature, good repeatability and can be industrialized. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the flexible self-supporting metal-organic framework-graphene oxide film comprising mixing raw materials, and vacuum filtering.
