▎ 摘  要

NOVELTY - The method involves dispersing graphene oxide in an organic solvent, and stirring the dispersion liquid to form uniform and stable film-casting solution. The solution is poured on a glass plate and wiped and dipped in a coagulating bath at room temperature. A polyether sulfone/graphene oxide compound ultra-filtration membrane is obtained after film self-breaking-off process, where mass percentage concentrations of the polyether sulfone, pore-forming solution and oxidized graphite alkene in the film-casting solution are 15-21 percent, 1-2 percent and 0.5-4.0 percent, respectively. USE - Method for preparing a polyether sulfone/graphene oxide compound ultra-filtration membrane. ADVANTAGE - The method ensures providing that prepared polyether sulfone/graphene oxide compound ultra-filtration membrane has better hydrophilicity, high porosity, anti-static performance and elasticity. The prepared ultra-filtration membrane has pure water flux rejection, and high mechanical performance. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating of a method for preparing a polyether sulfone/graphene oxide compound ultra-filtration membrane.
