Controllable directional transport of droplets is ubiquitous in nature and essential in many practical applications, which is based on disparity of physical structures and surface energy. Despite vast innovations in liquid transport strategies to generate liquid transport at a wide spectrum and various scales, the transport distance is limited due to the drawback of unwanted pinning of contact lines. Here, a continuous, directional, and long‐range transport system of fog droplets on integrating tapered surface inspired by spider silk and butterfly wing is reported. A new phenomenon occurs at the joint of integrating tapered surface: liquid film switches periodically between convex‐continuous and concave‐intermittent, which promotes the rapid surface reconstruction and fog droplet collection. The transport dynamics of fog droplets and rapid surface reconstruction facilitate highly effective water harvesting task.

集成锥形表面上的连续定向水传输

由于物理结构和表面能的差异，液滴的可控方向性传输本质上是普遍存在的，并且在许多实际应用中必不可少。尽管在液体输送策略上进行了巨大的创新以产生宽范围和各种规模的液体输送，但是由于不希望的接触线钉扎的缺点，输送距离受到限制。在这里，据报道，在蜘蛛丝和蝴蝶翼的启发下，在集成的锥形表面上雾滴的连续，定向和远距离传输系统。在集成锥形表面的接合处出现了一个新现象：液膜在凸连续和凹间歇之间周期性地切换，这促进了快速的表面重建和雾滴的收集。
