摘　　要：以铜网为基底,采用水热合成法构筑微纳米氧化锌粗糙结构表面,并用廉价无氟低表面能物质硬脂酸进行修饰改性,制备了具有超疏水性能的微纳米氧化锌铜网,并探讨所制备超疏水铜网在油水分离中的应用.利用扫描电子显微镜(SEM)、X射线粉末衍射仪(XRD)、接触角测试仪等对制备的超疏水铜网表面的形貌、化学组成与浸润性等进行表征与分析.结果表明,修饰后的铜网表面具有超疏水特性,接触角为160°,滚动角为8.5°,油水分离效率达到95.09%.The superhydrophobic micro zinc oxide copper net was synthisized by hydrothermal method on copper mesh,which then was modified with low-surface-energy monolayer of stearic acid to prepare superhydrophobic surface.At the same time,the application of the superhydrophobic copper mesh in the separation oil and water was discussed.The chemical compostion,surface morphology and infiltration of the samples were characterized by using XRD,SEM and contact angle measurement.The results showed that after the copper mesh surface was modified with super hydrophobicity,contact angle and roll angle of water was about 160°and 8.5°respectively,oil-water separation efficiency was up to 95.09%.
