Fabrication of superhydrophobic surfaces on copper foil with stearic acid

摘要

Superhydrophobic surface was prepared in hydrothermai method on copper substrate via immersing the clean pure copper substrate into the mixed solution of H_2O_2 and C_2H_5OH, and then the substrate was heated at 100 deg for 1.5 h, follwed by modifying with stearic acid. The product was characterized by scanning electron microscopy and X-ray photoelectron spectroscopy.
