Over the past few years, oil-water separation techniques have been widely researched due to influences of oil pollution. The oil pollution is significantly increasing day-by-day because of ever-increasing usage of oil in daily routine of humans and industrial activities. The separation of water from oil-water emulsions/mixtures through membrane technology has provided absolute necessary qualities such as low cost, eco-friendly, easy-operation and energy efficient. To build up the filter membranes with special super-wettability properties and bearing excellent multifunctional applications is highly attractive research area in current decade. However, evolution of membrane technology suffered many deficiencies including severe fouling, short-standing against high flow speed, surface wettability disorders, non-reusable and limited application. In this review article, we outline the recent advances in membrane technology with respect to special super-wettability properties, enhanced characteristics for purpose to serve oil-water separation, and more specifically its multifunctional applications. Therefore, this study is made for membranes having other than applications, in addition to oil-water separation. Further, the wetting phenomenon of these multifunctional membranes is addressed and highlighted the brief overview of surface wetting types including Superhydrophobic-Superoleophilic membranes, Superhydrophilic-Superoleophobic membranes, and Superhydrophilic-underwater Superoleophobic membranes. Moreover, relative fabrication procedures and multifunctional applications of developed multifunctional super-wetting membranes are also discussed along with wetting behavior. Finally, the current developments and achievements for oil-water separation multifunctional super-wetting membranes are concluded. Besides, it also explores the future challenges and obstacles associated to these membranes. Hence, this article provides brief overview of advancement of oil-water separation based multifunctional super-wetting membranes and ended with new thoughts of further modification/enhancement.

近年来，由于油污染的影响，油水分离技术得到了广泛的研究。由于人类和工业活动的日常使用中石油的使用不断增加，因此石油污染日益严重。通过膜技术从油水乳液/混合物中分离水提供了绝对必要的品质，例如低成本，环保，易于操作和节能。在过去的十年中，构建具有特殊的超湿性和优异的多功能应用性能的滤膜是非常有吸引力的研究领域。然而，膜技术的发展遭受许多缺陷，包括严重的结垢，对高流速的短期耐受性，表面润湿性障碍，不可重复使用和有限的应用。在这篇综述文章中，我们概述了膜技术在特殊的超湿性，增强的特性（用于油水分离），尤其是其多功能应用方面的最新进展。因此，本研究针对除油水分离以外的其他用途的膜。此外，解决了这些多功能膜的润湿现象并突出了对表面润湿类型的简要概述，包括超疏水-超亲油膜，超亲水-超疏油膜和水下超亲水-超疏油膜。此外，还讨论了开发的多功能超湿膜的相关制造程序和多功能应用以及湿润行为。最后，总结了油水分离多功能超湿膜的研究现状和成果。此外，它还探讨了与这些膜相关的未来挑战和障碍。因此，本文简要概述了基于油水分离的多功能超湿膜的进展，并以进一步修饰/增强的新思想作为结尾。
