超疏水性的自发破坏
Spontaneous Breakdown of Superhydrophobicity
摘要：
在某些情况下，水滴可以完全润湿微结构化超疏水表面。这种快速过程的{ \it动力学}通过超高速成像进行分析。取决于微结构的尺度，润湿前沿平滑地和圆形地传播，或者更有趣的是以{ \it逐步}的方式传播，导致{ \it方形}润湿区域的增长：垂直于前沿传播方向进入新的行需要毫秒，而一旦发生这种情况，行本身在微秒内填充（{ \it "拉链“}）
英文摘要：
In some cases water droplets can completely wet micro-structured superhydrophobic surfaces. The {\it dynamics} of this rapid process is analyzed by ultra-high-speed imaging. Depending on the scales of the micro-structure, the wetting fronts propagate smoothly and circularly or -- more interestingly -- in a {\it stepwise} manner, leading to a growing {\it square-shaped} wetted area: entering a new row perpendicular to the direction of front propagation takes milliseconds, whereas once this has happened, the row itself fills in microseconds ({\it ``zipping''})
