超疏水-超亲油材料在油水分离中的研究进展

综述了超疏水-超亲油油水分离材料的研究进展及其在油水分离中的应用。首先介绍了油水分离材料的特殊润湿性的基本理论和设计理念,主要包括Young方程、Wenzel模型、Cassie模型以及制备油水分离材料的两种途径。然后全面介绍了金属网膜类、纺织品类、合成膜类等二维结构的油水分离材料,以及海绵、泡沫、气凝胶等三维网络状类油水分离材料和智能型油水分离材料。最后总结了目前在油水分离这一领域存在的一些问题,主要是油水分离的基本机制和理论研究不够完善,并指出开发和研究能够分离特殊油品的材料以及智能响应性可控的油水分离材料仍然是一大挑战。

Progress of superhydrophobic-superoleophilic materials for oil/water separation

This paper reviews the research progress of superhydrophobic-superoleophilic materials and its application in the oil/water separation.First, the basic theory of special wettability and design concept for oil-water separation materials are introduced, including Young equation, the Wenzel model, Cassie model as well as the preparation methods of oil-water separation materials.Then, two-dimensional oil/water separation materials, such as metal membranes, textiles and synthetic membrane materials, and three-dimensional networks, including sponge, foam, aerogel, and intelligent oil/water separation materials are comprehensively reviewed.Finally, we summarized the problems which exist in the field of oil/water separation, for example, the basic mechanism of oil-water separations are need to be further improved.In addition, research and development of materials for separating special oils from water and intelligent oil/water separation materials are still big challenges.
