摘　　要：采用了一种简单的化学刻蚀法制备具有超疏水性能的铜(Cu)表面。用K_(2)S_(2)O_(8)和NaOH的混合液为刻蚀液对Cu样品进行刻蚀,制备了具有超疏水性能的Cu表面,接触角达165.52°。用扫描电子显微镜、接触角测量仪对样品进行表征,并分析超疏水结构形成的机理;通过改变刻蚀条件(刻蚀液浓度、刻蚀时间、烘干温度)来分析不同刻蚀条件对制备超疏水样品润湿性的影响。结果表明,当NaOH浓度为0.500 mol/L,K_(2)S_(2)O_(8)浓度为0.025 mol/L,在25℃的环境下刻蚀60 min时,接触角达到了165.52°,制备的超疏水表面均匀的出现了无序排列的片状结构。In this paper,a simple preparation of a super-hydrophobic surface of copper with chemical etching was developed.Copper(Cu)samples were etched with a mixture of K_(2)S_(2)O_(8)and NaOH as etching solution to prepare a copper surface with superhydrophobic properties with a contact angle of 165.52°.The super-hydrophobic structure was characterized by scanning electron microscopy and contact angle measurement on the samples.The mechanism of the formation of the super-hydrophobic structure was also analyzed.The effect on preparation superhydrophobic wetting of the sample was studied by changing the etching conditions(concentration of etching solution,etching time,drying temperature).The results showed that when the NaOH concentration was 0.500 mol/L and the K_(2)S_(2)O_(8)concentration was 0.025 mol/L,a super-hydrophobic surface appeared at 25℃ under 60 min with the contact angle 165.52°.The prepared superhydrophobic surface uniformly appeard in a disorderly arranged sheet structure.
