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.
