In this study, we developed a one-step method for fabricating hydrophobic surfaces on copper (Cu) substrates. Cuprous oxide (CuO) with low free energy was successfully formed after low-fluence laser direct irradiation. The formation of CuO enhanced the hydrophobicity of the Cu substrate surface, and the contact angle linearly increased with the proportion of CuO. The CuO fabricated by low-fluence laser treatment showed the same crystal plane orientation as the pristine Cu substrate, implying an epitaxial growth of CuO on a Cu substrate.
在本研究中，我们开发了一种在铜（Cu）基底上制备疏水表面的一步法。在低能量密度激光直接辐照后成功形成了具有低自由能的氧化亚铜（CuO）。CuO的形成增强了Cu基底表面的疏水性，并且接触角随CuO的比例呈线性增加。通过低能量密度激光处理制备的CuO显示出与原始Cu基底相同的晶面取向，这意味着CuO在Cu基底上的外延生长。
