摘要：
本发明属于环境功能材料制备技术领域，具体涉及氧化石墨烯/异硬脂酸复合分离膜及其制备方法及应用。本发明的氧化石墨烯/异硬脂酸复合分离膜的制备方法具体为：将氧化石墨烯溶于无水乙醇溶液中；再将异硬脂酸溶于无水乙醇中；将上述两种溶液混合均匀，水浴加热反应，真空干燥；将得到的氧化石墨烯/异硬脂酸复合物溶于去离子水中，磁力搅拌；以商业混合纤维素膜为基膜，真空抽滤，真空干燥，得到的氧化石墨烯/异硬脂酸复合分离膜。本发明的制备方法简单，易于操作；制备的复合分离膜具有优异的热稳定性，分离稳定性较佳，截留率最高达到93.7%，能够有效去除水溶液中油水乳液，有望应用于工业生产中。
摘要（英）：

The invention belongs to the technical field of environmental functional material preparation, and particularly relates to a graphene oxide/isostearic acid composite separation membrane, a preparationmethod and application thereof. The preparation method of the graphene oxide/isostearic acid composite separation membrane provided by the invention specifically comprises the following steps: dissolving graphene oxide in an anhydrous ethanol solution; dissolving isostearic acid in anhydrous ethanol; uniformly mixing the above two solutions, heating and reacting in a water bath, and drying in a vacuum; dissolving the obtained graphene oxide/isostearic acid compound in deionized water and magnetically stirring; taking a commercial mixed cellulose film as a base membrane, filtering in a vacuum,and drying in a vacuum to obtain the graphene oxide/isostearic acid composite separation membrane. The preparation method is simple and easy to operate, and the prepared composite separation membranehas excellent thermal stability, and good separation stability, the rejection rate is up to 93.7%, the composite separation membrane can effectively remove an oil-water emulsion in the aqueous solution, and is expected to be applied to industrial production.
