<正>Development of oil–water separation materials has a significant influence on the treatment of water contamination and the purity of oil products [1–4]. The frequency of oil spills is closely related to the human activity, such as fisheries, mariculture, and the marine environment. Meanwhile, small amounts of water in lubricants or fuel oils may endanger transportation safety in the transportation industry. Compared to distillation or other separation means,membrane filtration technology is widely used in oil–water separation due to the advantages of high separation efficiency and low-energy consumption.
