摘要

从自清洁和防结冰到防雾和油水分离,金属表面在众多应用中发挥着至关重要的作用。要提高金属表面在这些领域的性能,就必须对其润湿性进行调节。本文提出了一种利用纳秒激光烧蚀的金属表面润湿性多态调节方法。通过在金属表面形成非均匀的微结构,可以增加固相和液相之间的接触面积,从而获得超亲水性能(接触角 (CA) 在 4.6° 至 8.5° 之间)。相反,均匀微结构的形成会导致固液接触面积减小,从而使金属表面具有亲水性(CA = 12.2°-53°)。此外,通过对具有均匀微观结构的表面进行热处理,可以促进有机物的吸附,同时降低表面能。这一过程可使金属表面获得疏水特性(CA = 92.1°-133.5°),并通过 "气垫效应 "得到促进。在疏水表面的基础上,硬脂酸改性可进一步降低表面能,最终使金属表面具有超疏水特性(CA = 150.1°-152.7°,滑动角 = 3.8°)。性能测试验证了制造出的超疏水表面的耐用性和自清洁效果,同时也突出了超亲水表面的卓越防雾性能。这些发现有力地表明了这些表面在各种工程应用中的巨大潜力。

Wettability regulation from superhydrophilic to superhydrophobic via nanosecond laser ablation

Metal surfaces play a crucial role in numerous applications, from self-cleaning and anti-icing to anti-fogging and oil-water separation. The regulation of their wettability is essential to enhance their performance in these areas. This paper proposes a multi-state regulation method for metal surface wettability, leveraging nanosecond laser ablation. By creating non-uniform microstructures on a metal surface, the contact area between the solid and liquid phases can be increased, resulting in the attainment of superhydrophilic properties (contact angle (CA), ranging from 4.6° to 8.5°). Conversely, the construction of uniform microstructures leads to a decreased solid-liquid contact area, thereby rendering the metal surface hydrophilic (CA = 12.2°–53°). Furthermore, through heat treatment on a surface with uniform microstructures, organic matter adsorption can be promoted while simultaneously reducing surface energy. This process results in the metal surface acquiring hydrophobic properties (CA = 92.1°–133.5°), facilitated by the “air cushion effect.” Building on the hydrophobic surface, stearic acid modification can further reduce surface energy, ultimately bestowing the metal surface with superhydrophobic properties (CA = 150.1°–152.7°, and sliding angle = 3.8°). Performance testing has validated the durability and self-cleaning effectiveness of the fabricated superhydrophobic surface while also highlighting the excellent anti-fog performance of the superhydrophilic surface. These findings strongly indicate the immense potential of these surfaces in various engineering applications.
