近年来,由于频繁发生石油泄漏,油水分离已成为全球性挑战。在这里,我们展示了一种水下超疏油银涂层网,它是通过简单的电流交换反应制造的。该网格用于研究重力驱动的油/模拟海水分离,分离效率可达到94.0%以上。此外,Ag涂层网在45次分离循环后仍能保持这种高分离效率。此外,镀银网在恶劣条件下表现出优异的环境稳定性。我们相信Ag涂层网可用于开发油/水分离功能材料。
Recently, oil/water separation has become a global challenge due to frequent oil spills. Herein, we demonstrate an underwater superoleophobic Ag coated mesh, which is fabricated by a facile galvanic exchange reaction. The mesh was used to study gravity-driven oil/simulated seawater separation, in which a separation efficiency of above 94.0% could be achieved. In addition, the Ag coated mesh can maintain this high separation efficiency after 45 separation cycles. Furthermore, the Ag coated mesh exhibits excellent environmental stability under harsh conditions. We believe that the Ag coated mesh can be applied for the development of functional materials for oil/water separation.
