Oil–water separation is an urgent issue due to the frequently occurred oil leakages and increasing discharge of oily wastewater. The pollutional and wastewater can not only damage the environment, but endanger human health. Owing to the small particle size of the oil contamination, it is still a challenge for the separation of oil–water emulsion. In this study, we developed a facile strategy to prepare a hydrophilic polyvinylpyrrolidone/polyacrylonitrile (PVP/PAN) nanofibrous membrane for oil–water mixture and emulsion separation. The lowest water contact angle on the membrane surface can achieve 16.7°, thus the membranes can effectively resist the oil contamination on them. Moreover, the membrane can efficiently separate oil–water mixtures and emulsion by gravity. In addition, it can separate oil–water mixtures in harsh conditions (pH = 1 and 14). Membranes prepared in this work would hold a great potential in the practical use of water treatment and environmental industry.

耐油污的PVP / PAN电纺膜，用于高效的油水混合物和乳液分离

由于经常发生漏油和含油废水排放增加，油水分离是一个紧迫的问题。污染和废水不仅会破坏环境，而且还会危害人类健康。由于油污的粒径很小，因此分离油水乳液仍然是一个挑战。在这项研究中，我们开发了一种简便的策略来制备亲水性聚乙烯吡咯烷酮/聚丙烯腈（PVP / PAN）纳米纤维膜，用于油水混合物和乳液分离。膜表面的最低水接触角可达到16.7°，因此膜可有效抵抗其上的油污。而且，该膜可以通过重力有效地分离出油水混合物和乳液。此外，它可以在恶劣条件下（pH = 1和14）分离油水混合物。
