The frequent occurrence of crude oil spills and the indiscriminate discharge of oily wastewater have caused serious environmental pollution. The existing separation methods have some defects and are not suitable for complex oil-water emulsions. Therefore, the efficient separation of complex oil-water emulsions has been of great interest to researchers. Asymmetric wettable Janus materials, which can efficiently separate complex oil-water emulsions, have attracted widespread attention. This comprehensive review systematically summarizes the research progress of asymmetric wettable Janus materials for oil-water separation in the last decade, and introduces, in detail, the preparation methods of them. Specifically, the latest research results of two-dimensional Janus materials, three-dimensional Janus materials, smart responsive Janus materials, and environmentally friendly Janus materials for oil-water separation are elaborated. Finally, ongoing challenges and outlook for the future research of asymmetric wettable Janus materials are presented.
原油泄漏频繁发生，含油废水的任意排放，造成了严重的环境污染。现有的分离方法存在一些缺陷，不适合复杂的油水乳液。因此，高效分离复杂的油水乳液一直是研究人员关注的焦点。具有不对称润湿性的 Janus 材料可以高效分离复杂的油水乳液，引起了广泛关注。本文系统地总结了过去十年中用于油水分离的不对称润湿性 Janus 材料的研究进展，并详细介绍了它们的制备方法。具体而言，详细阐述了二维 Janus 材料、三维 Janus 材料、智能响应 Janus 材料和环保型 Janus 材料在油水分离方面的最新研究成果。最后，提出了不对称润湿性 Janus 材料未来研究的挑战和展望。
