SignificanceAdjusting the floating states when objects float on water shows great potential for assembly, mineral flotation, nanostructured construction, and floating robot design, but the real-time regulation of floating states is challenging. Inspired by the different floating states of a falling fruit, we propose a facile strategy to transform the object between different floating states based on a three-segment three-phase contact line evolution. In addition, the potential of floating state transformation in solar-powered water evaporation, interface catalysis, and drug delivery is demonstrated. These findings provide insights into floating regulation and show great potential for floating-related applications.
当物体在水面上漂浮时，调整其浮动状态在组装、矿物浮选、纳米结构构建和浮动机器人设计方面具有很大的潜力，但实时调节浮动状态具有挑战性。受下落水果不同漂浮状态的启发，我们提出了一种基于三段三相接触线演变来实现物体在不同漂浮状态之间转换的简便策略。此外，还展示了在太阳能水蒸发、界面催化和药物输送方面的漂浮状态转换潜力。这些发现为漂浮调节提供了新的见解，并展示了在与漂浮相关的应用方面的巨大潜力。
