In recent years, wastewater containing various oils, produced in many industrial processes, such as petrochemical, metallurgy, coal tar, textile, steel and metal finishing, and discharged to the environment without further treatment has brought about great harm to the ecosystem we live in and raised serious concerns in the public. To address this issue, development of energy-efficient methods for oil/water separation has become an important task. These methods generally realize effective oil/water separation by either filtration or absorption of water or oils from the mixtures selectively, using materials and devices with special wetting properties. In this presentation, we report our recent progress in the development of coating materials used for oil/water separation by filtration. These coatings can render the separation mesh flexible,1 highly efficient,2 and foul-resistant.
