Static Hydrophobic Cuprous Oxide Surface Fabricated via One-Step Laser-Induced Oxidation of a Copper Substrate

In this study, we developed a one-step method for fabricating hydrophobic surfaces on copper (Cu) substrates. Cuprous oxide (Cu(2)O) with low free energy was successfully formed after low-fluence laser direct irradiation. The formation of Cu(2)O enhanced the hydrophobicity of the Cu substrate surfac...

description In this study, we developed a one-step method for fabricating hydrophobic surfaces on copper (Cu) substrates. Cuprous oxide (Cu(2)O) with low free energy was successfully formed after low-fluence laser direct irradiation. The formation of Cu(2)O enhanced the hydrophobicity of the Cu substrate surface, and the contact angle linearly increased with the proportion of Cu(2)O. The Cu(2)O fabricated by low-fluence laser treatment showed the same crystal plane orientation as the pristine Cu substrate, implying an epitaxial growth of Cu(2)O on a Cu substrate.
