Our world is facing continued challenges of environmental and ecological pollutions due to human and industrial activities. One of the major threats is oily wastewater mainly discharged from oil fields, refineries, automobile, palm oil industries, and many others. Membrane-based technology offers an almost complete separation of oil from water. However, the technology is facing the challenge of maintaining performance over long periods of operation caused by membrane fouling as a result of interaction between oil droplets and the membrane surface. This attracts research interest mainly on developing customized polymeric, ceramic well as a metallic-based membrane material for improved performance. This paper reviews the recent advances of membrane material developments with the focus on methods of improving the surface chemistry, structure, and hydrodynamics and their implication on the filtration performances.

由于人类和工业活动，我们的世界正面临着环境和生态污染的持续挑战。主要威胁之一是含油废水，主要从油田、炼油厂、汽车、棕榈油工业和许多其他行业排放。基于膜的技术几乎可以将油与水完全分离。然而，由于油滴和膜表面之间的相互作用导致膜污染，该技术正面临在长时间运行中保持性能的挑战。这吸引了研究兴趣，主要是开发定制的聚合物、陶瓷以及金属基膜材料以提高性能。本文回顾了膜材料发展的最新进展，重点是改善表面化学、结构、
