成功制备了一种超两亲性的聚偏氟乙烯（PVDF）膜，该膜在水中具有超疏油性，在油下具有超疏水性。由于具有可切换的输运性能，该膜适用于分离液滴尺寸大于20 nm的各种水包油和油包水乳剂，具有优异的渗透性和防污性，分离效率高。
A superamphiphilic poly(vinylidene fluoride) (PVDF) membrane with superoleophobicity under water and superhydrophobicity under oil is successfully prepared. Due to the switchable transport performance, the membrane is applicable to the separation of various oil-in-water and water-in-oil emulsions with a droplet size greater than 20 nm, and shows superior permeability and antifouling properties, as well as a high separation efficiency.
