在这项研究中，提出了一种简单而详细的策略，利用飞秒激光烧蚀制备具有可控附着力的超疏水铝表面。研究了飞秒激光加工的关键参数，包括扫描速度、激光功率和激光间隔对激光烧蚀表面润湿性能的影响。结果表明，通过调整激光加工工艺参数，可以有效地将水与超疏水表面的附着力从极低的附着力调整为高附着力。同时，对激光烧蚀表面润湿行为的变化机理进行了探讨。这些具有可调附着力的超疏水表面在自清洁表面、油水分离、防冰表面和液体输送等方面具有潜在的应用前景。(C)2017爱思唯尔有限公司。保留所有权利。
In this study, a facile and detailed strategy to fabricate superhydrophobic aluminum surfaces with controllable adhesion by femtosecond laser ablation is presented. The influences of key femtosecond laser processing parameters including the scanning speed, laser power and interval on the wetting properties of the laser-ablated surfaces are investigated. It is demonstrated that the adhesion between water and superhydrophobic surface can be effectively tuned from extremely low adhesion to high adhesion by adjusting laser processing parameters. At the same time, the mechanism is discussed for the changes of the wetting behaviors of the laser-ablated surfaces. These superhydrophobic surfaces with tunable adhesion have many potential applications, such as self-cleaning surface, oil-water separation, anti icing surface and liquid transportation.
