▎ 摘　　要

NOVELTY - Preparation of composite film of oxidized graphene skeleton material involves (a) oxidizing the graphite powder to obtain oxidized graphene, (b) preparing graphene oxide skeleton material by carrying out solvothermal reaction of double active component and oxidized graphene, (c) mixing uniformly oxidized graphene skeleton material suspension and polymer solution, and (d) depositing composite film of an oxidized graphene skeleton material on a porous support. USE - Preparation of composite film of oxidized graphene skeleton material used for separating azeotrope from pervaporation process in liquid phase separation (claimed). ADVANTAGE - The method enables preparation of composite film of oxidized graphene skeleton material having excellent mechanical property and high selectivity.
