油水混合物不仅对生态环境造成破坏,同时也危及人类身体健康。针对油水混合物进行高效分离,不仅可以实现油、水资源的重复使用,还可有效地避免其直接排放所造成的严重环境污染问题。因此开发高效油水分离材料对于资源节约,实现双碳目标和践行习近平总书记“绿水青山就是金山银山”理念具有重要意义。特殊润湿性因其对油水两相的响应不同在油水分离领域中显示出良好的应用前景,具备该特性的油水分离膜材料分离效率高、分离速度快、能耗低、可扩展性好、操作简单且可回收利用,因此针对油水分离膜材料制备过程中基底材料选择的不同,详细介绍了以金属、聚合物、生物质和无机物为基底材料制备油水分离膜材料及其应用研究进展,并对油水分离膜材料领域研究进行展望。
Oil-water mixtures are not only damaging to the ecological environment,but also posing risks to human health.The efficient separation of oil-water mixtures can not only enable the reuse of oil and water resources,but also effectively avoid the serious environmental pollution caused by their direct discharge.Therefore,the development of highly efficient oil-water separation materials is of great importance for the conservation of resources,the realisation of the double carbon goal and the implementation of general secretary Xi's concept of “green water and green mountains are the silver and gold mountains”.The special wettability shows good application prospects in the field of oil-water separation due to its different response to oil and water phases,and the oil-water separation membrane materials with this characteristic have high separation efficiency,fast separation speed,low energy consumption,good scalability,simple operation and can be recycled.In this paper,the preparation of oil-water separation membrane materials based on different substrate materials such as metals,polymers,biomass,and inorganic substances,as well as their research and application progress were presented in detail,and an outlook on the research directions in the field of oil-water separation membrane materials was given.
