摘要
Tuning surface wettability is of great interest for both scientific research and practical applications. We report a facile electrochemical route for tuning the superhydrophobic surface of stearic acid (SA) modified copper with over-oxidized polypyrrole (OPPy). A systematic study was performed on the relationship between pyrrole concentrations and wetting states of SA modified copper surface. The wettability of the SA modified copper surface was monotonically converted from superhydrophobicity to hydrophilicity by increasing the pyrrole concentration during the process of electrochemical deposition.
