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100～200μm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。
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.
