摘要： 以棕榈酸-乙醇溶液为疏水剂，利用直接浸泡法在纯铜表面上构筑了超疏水薄膜。 纯铜表面超疏水薄膜的最佳制备条件为：0.03 mol/L棕榈酸-乙醇溶液，室温（20～22 ℃），浸泡144 h。 通过扫描电子显微镜、接触角测量仪、红外光谱仪和高精密电子天平对超疏水表面进行了表征和分析。 实验结果表明，纯铜试样表面形成了100～200 μm大小的草状棕榈酸铜微簇，接触角达到了150°，其具有较好的抗结垢性能。

Abstract: The superhydrophobic film on copper surface was fabricated by immersing copper substrate in palmitic acid dissovled in ethanol. The optimal conditions for fabricating the superhydrophobic film on copper are: 0.03 mol/L palmitic acid in ethanol solution, temperature of 20～22 ℃ and 144 h of immersion. The resultant superhydrophobic film was characterized and analyzed by means of scanning electron microscopy(SEM), contact angle goniometer, Fourier-transform infrared spectrometer(FTIR) and high precision electronic balance, respectively. The results showed that it was the grass-like Cu(CH3(CH2)14COO)2 microcluster with dimensional size in the range of 100～200 μm that was responsible for its hydrophobic property. The water contact angle of superhydrophobic surface is 150°. The superhydrophobic surface on copper showed superior anti-fouling performance.

Key words: superhydrophobic films, copper, solution-immersion, anti-fouling
