Progress of oil/water separation membrane

油水分离膜由于具有通量高、截留性能好和应用范围广的特性,目前成为油水分离材料研究的热点之一.本文论述了高抗污分离膜、高通量分离膜、高精准分离膜、高适用分离膜和刺激响应分离膜的研究进展,讨论了目前超浸润油水分离膜材料的分离机理,提出了油水分离膜目前面临的长效抗污关键问题,并提出探索新型的聚并破乳机制以及设计并构筑高抗污表面,是未来油水分离膜突破应用瓶颈需要发展的重点.

Recently, oil/water separation membrane has been one of the hotspots in the field of oil/water separation materials due to its high permeability, high separation efficiency and wide applications. The progress of separation membranes with antifouling performance, high permeability, high separation efficiency, practicability and stimuli-responsive performances was reviewed? The general issues and mechanism during the oil/water separation was discussed. The key problems of long-term anti-fouling currently faced by oil-water separation membranes were put forward, and it was proposed to explore a new type of coalescence-demulsification mechanism and to construct a high anti-fouling surface, which is the focus of future development of oil-water separation membranes.
