Abstract

A composite material is described that is an effective filter to separate oil from an oil and water emulsion or other mixtures of oil and water. The composite material has a permeable substrate, such as fabric, that is coated with a selectively-permeable coating. The composite material allows only oil to pass through, while water is prevented from passing through. The composite material has two main components, a hydrophobic component and an emulsion-destabilizing component.
