摘要: 通过对比分析不同激光脉宽制备的微结构几何精度与润湿性能,获取了微结构几何精度与润湿性能的关联规律。研究发现,减小激光脉宽有助于提高微结构的几何精度,增强表面疏水性能;皮秒激光加工在微结构底部形成了规则的乳突阵列结构,使其具有最优的疏水性能。

Abstract: By comparing and analyzing the geometric accuracy and wettability of microstructures prepared with different laser pulse widths, the relationship between geometric accuracy and hydrophobicity was established. The results demonstrate that reducing the laser pulse width improves the geometric accuracy of microstructures and enhances their surface hydrophobicity. The picosecond-laser-fabricated microstructures with regular papillae arrays at the bottom region exhibit the optimal water-repellent properties.

Key words: microstructure, correlation mechanism, machining accuracy, hydrophobicity, laser induced
