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.
成功制备了一种水下超疏油、油上超疏水的超亲油聚偏氟乙烯(PVDF)膜。由于具有可切换的传输性能,该膜适用于分离各种大于 20nm 粒径的油包水和水包油乳液,表现出优异的渗透性和抗污染性以及高分离效率。
