A thermoresponsive Poly(N‐isopropylacrylamide) (PNIPAAm)‐modified nylon membrane was fabricated via hydrothermal route. Combining rough structure, proper pore size, and thermoresponsive wettability, the membrane can separate at least 16 types of stabilized oil‐in‐water and water‐in‐oil emulsions at different temperatures. Below the LCST (ca. 25 °C), the material exhibits hydrophilicity and underwater superoleophobicity, which can be used for the separation of various kinds of oil‐in‐water emulsions. Above the LCST (ca. 45 °C), the membrane shows the opposite property with high hydrophobicity and superoleophilicity, and it can then separate stabilized water‐in‐oil emulsions. The material exhibits excellent recyclability and high separation efficiency for various kinds of emulsions and the hydrothermal method is facile and low‐cost. The membrane shows good potential in real situations such as on‐demand oil‐spill cleanup, industrial wastewater treatment, remote operation of oil/water emulsion separation units, and fuel purification.

聚合物装饰膜具有可切换润湿性的热驱动可控乳液分离

热敏聚（N异丙基丙烯酰胺（PNIPAAm）改性的尼龙膜是通过水热法制备的。结合粗糙的结构，合适的孔径和热响应性可湿性，该膜可以在不同温度下分离至少16种类型的稳定化的水包油型和油包水型乳液。在LCST以下（约25°C），该材料具有亲水性和水下超疏油性，可用于分离各种水包油型乳液。在LCST（约45°C）以上，该膜表现出相反的特性，具有高疏水性和超亲油性，然后可以分离稳定的油包水型乳液。该材料对各种乳液显示出优异的可回收性和高分离效率，并且水热法简便易行且成本低廉。
