▎ 摘　　要

NOVELTY - Preparation of super-hydrophobic porous polymer involves mixing dopant solution and cellulose acetate to obtain a mixture, mixing and refrigerating the mixture and alcohol compound to obtain a refrigerated product, performing solvent exchange of the refrigerated product, and freeze-drying. The solute in dopant solution is chosen from ZIF-8 and/or graphene. USE - Preparation of super-hydrophobic porous polymer used in material and device for separaing oil-water (all claimed). ADVANTAGE - The method provides preparation and method of super-hydrophobic ZIF-8-doped cellulose acetate porous polymer has simple and rapid process, low cost, safely and greenly treat oil stains in water, and is suitable for large-scale production.
