在本文中，我们展示了通过激光微结构制造疏水性聚合物表面。通过使用来自 532 nm 调 Q 锁模 Nd:YAG 激光器的 70 ps 脉冲，我们能够产生不同宽度和间距的凹槽，从而形成方形柱图案。我们研究了形态对水的表面静态接触角的依赖性，表明它与 Cassie-Baxter 模型一致。我们展示了超疏水聚合物表面的制造，其水接触角为 157 度。这里提出的表面结构化方法似乎是控制聚合物表面润湿性能的一个有趣的选择。 (C) 2010 Elsevier B.V. 保留所有权利。
In this paper we show the fabrication of hydrophobic polymeric surfaces through laser microstructuring. By using 70-ps pulses from a Q-switched and mode-locked Nd:YAG laser at 532 nm, we were able to produce grooves with different width and separation, resulting in square-shaped pillar patterns. We investigate the dependence of the morphology on the surface static contact angle for water, showing that it is in agreement with the Cassie-Baxter model. We demonstrate the fabrication of a superhydrophobic polymeric surface, presenting a water contact angle of 157 degrees. The surface structuring method presented here seems to be an interesting option to control the wetting properties of polymeric surfaces. (C) 2010 Elsevier B.V. All rights reserved.
