Abstract

We report a novel method for the fabrication of copper surfaces with controlled wettability. Through modification of the nanostructured copper substrates with mixed thiol molecules of HS(CH₂)₉CH₃ and HS(CH₂)₁₁OH, surfaces with controlled wettability from superhydrophobicity to superhydrophilicity can be achieved by simply controlling the concentration of HS(CH₂)₁₁OH in the modified solution. The controllability of the surfaces wettability can be ascribed to the combined effect of the surface chemistry variation and the hierarchical micro/nanostructures on the substrates. Especially the presence of hierarchical micro/nanostructures, which can provide a better control of the surface wettability between the two extremes: superhydrophobicity and superhydrophilicity.
