超疏水表面对穿刺的极端抵抗力：与冲击/弹跳跌落试验相关的可逆电润湿
Extreme resistance of super-hydrophobic surfaces to impalement: reversible electrowetting related to the impacting/bouncing drop test
摘要：
采用液滴冲击实验和电润湿实验对超疏水硅纳米线的润湿性能进行了比较。显示了EW和跌落冲击上的抗刺穿性之间的相关性。结果表明，随着纳米线长度和密度的增加，跌落冲击阈值和EW不可逆性增加，接触角滞后减小。这表明NW网络的结构可以允许部分刺穿，因此保持可逆性，EW的作用方式与外部压力相同。我们的表面中最坚固的显示出高于35 kPa的刺穿阈值，而迄今为止测试的大多数超疏水表面的刺穿阈值小于10 kPa。
英文摘要：
The paper reports on the comparison of the wetting properties of super-hydrophobic silicon nanowires (NWs), using drop impact impalement and electrowetting (EW) experiments. A correlation between the resistance to impalement on both EW and drop impact is shown. From the results, it is evident that when increasing the length and density of NWs: (i) the thresholds for drop impact and EW irreversibility increase (ii) the contact-angle hysteresis after impalement decreases. This suggests that the structure of the NWs network could allow for partial impalement, hence preserving the reversibility, and that EW acts the same way as an external pressure. The most robust of our surfaces show a threshold to impalement higher than 35 kPa, while most of the super-hydrophobic surfaces tested so far have impalement threshold smaller than 10 kPa.
