越来越多的石油泄漏事故对我们的水生环境造成了灾难性的影响。近年来，用于油水分离的特殊可湿性材料受到了广泛的关注。由于它们对水和油的相反亲和性，即疏水亲油，或亲水疏油，这些材料可以用来从油/水混合物中只去除一个相，同时排斥另一个相，从而实现油/水的选择性分离。此外，表面化学和表面结构之间的协同作用可以进一步促进超润湿行为，从而提高分离效率。本文对近年来开发的用于油水选择性分离的特殊润湿性材料进行了综述和讨论。这些材料可以根据其油水分离机制进行分类，即过滤和吸收。在每个部分，将突出有代表性的研究，重点是材料的润湿特性和创新方面。最后，简要介绍了这一新兴研究领域面临的挑战和未来的研究方向。
The increasing number of oil spill accidents have a catastrophic impact on our aquatic environment. Recently, special wettable materials used for the oil/water separation have received significant research attention. Due to their opposing affinities towards water and oil, i.e., hydrophobic and oleophilic, or hydrophilic and oleophobic, such materials can be used to remove only one phase from the oil/water mixture, and simultaneously repel the other phase, thus achieving selective oil/water separation. Moreover, the synergistic effect between the surface chemistry and surface architecture can further promote the superwetting behavior, resulting in the improved separation efficiency. Here, recently developed materials with special wettability for selective oil/water separation are summarized and discussed. These materials can be categorized based on their oil/water separating mechanisms, i.e., filtration and absorption. In each section, representative studies will be highlighted, with emphasis on the materials wetting properties and innovative aspects. Finally, challenges and future research directions in this emerging and promising research field will be briefly described.
