摘　　要：为使铜网能用于油水分离,实验利用六次甲基四胺溶液和硝酸锌溶液反应处理铜网,最后用十六烷基三甲氧基硅烷对其进行表面改性,制备了具有超疏水性能的铜网。利用扫描电镜、X射线衍射仪对样品的表面形貌以及成分进行分析,并对其润湿性、重复使用性能以及油水分离性能进行了测试。结果表明,实验制备的超疏水铜网与水的接触角可达151°左右,对石油醚、正己烷、正辛烷、正庚烷、煤油等不同油类的分离效率均在95%以上;铜网重复使用100次以后,油水分离效率仍在90%以上,仍具有良好的油水分离性能和重复使用性能。In order to enable the copper mesh to be used for oil-water separation, the experiment for the copper mesh was carried out by reaction of hexamethylenetetramine solution with zinc nitrate solution, and the surface modification was carried out with cetyltrimethoxysilane. Finally, the copper mesh with super hydrophobic properties was successfully prepared. The surface morphology and composition of the samples were analyzed by SEM and XRD, and the wettability, reusability and oil-water separation performance were tested. The results show that the contact angle of the superhydrophobic copper mesh prepared by the experiment with water can reach 151°, and the separation efficiency of different oils such as petroleum ether,n-hexane, n-octane, n-heptane and kerosene is above 95%. When the copper mesh is reused for 100 times, the oil-water separation efficiency is still above 90%, which has a good oil-water separation efficiency and reusability.
