以铜网为基底,采用氧化法构筑微纳米粗糙结构表面,并用廉价无氟低表面能物质硬脂酸进行修饰,制备了具有超疏水特性的铜网。考察了制备条件对铜网疏水性能的影响,并利用扫描电子显微镜(SEM)、X射线粉末衍射仪(XRD)、接触角测试仪等对所得超疏水铜网表面的形貌、化学组成及浸润性等进行表征,同时探讨超疏水铜网在油水分离中的应用效果。结果表明,所制备的铜网表面具有超疏水特性,接触角为155°,成功应用于油水混合液的分离,油水分离效率达到了95.17%。
Based on the copper mesh, the surface of micro-nano rough structure was formed by oxidation method and modified with low-cost fluorine-free low surface energy material stearic acid to prepare a copper net with superhydrophobic properties. The effects of preparation conditions on the hydrophobic properties of copper mesh were investigated. The morphology, chemical composition and wettability of the superhydrophobic copper mesh were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and contact angle tester Sex and other characterization, at the same time to explore the effect of superhydrophobic copper network in oil-water separation. The results show that the surface of the prepared copper net has superhydrophobic character and the contact angle is 155 °. It has been successfully applied in the separation of oil and water mixture with an oil-water separation efficiency of 95.17%.
