油水分离不仅是科学研究的重要领域，而且对于解决工业含油废水和溢油污染以及环境保护等实际应用也具有重要意义。近年来，关于特殊润湿性在油水分离中的作用的研究引起了人们的广泛关注。本文综述了油水分离专用可湿性材料的设计、制备、应用及最新进展。根据分离类型的不同，我们将其分为三个部分：具有超疏水和超亲油性的“除油”型材料(选择性地过滤或吸收油水混合物中的油)、具有超亲水和超疏油性质的“除水”型材料(选择性地将水从油水混合物中分离出来)和智能可控分离材料。在每个部分中，我们详细介绍了代表性的工作，介绍了设计思想，概述了它们的制备方法，并讨论了特殊的润湿性在分离中的作用。最后，讨论了本课题面临的挑战和对未来的展望。
Oil/water separation is an important field, not only for scientific research but also for practical applications aiming to resolve industrial oily wastewater and oil-spill pollution, as well as environmental protection. Recently, research into the role of special wettability for oil/water separation has attracted much attention. In this review we summarize the design, fabrication, applications and recent developments of special wettable materials for oil/water separation. Based on the different types of separation, we organize this review into three parts: “oil-removing” type materials with superhydrophobicity and superoleophilicity (that selectively filter or absorb oil from oil/water mixtures), “water-removing” type materials with superhydrophilicity and superoleophobicity (that selectively separate water from oil/water mixtures), and smart controllable separation materials. In each section, we present in detail the representative work, introduce the design idea, outline their fabrication methods, and discuss the role of special wettability on the separation. Finally, the challenges and outlook for the future of this subject are discussed.
