气体捕获-通常是超疏水（SHPo）-表面是有用的水下应用，只有当他们的胸甲持续。由于在大多数实际条件下胸甲不幸地消失，已经报道了各种主动方法来供应充足的气体，包括基于自调节电解的半活性SHPo表面。在这里，我们报告了两个主要进展：（i）一个自供电的胸甲恢复机制，消除了对外部电源的需要;（ii）一步成型工艺，大规模生产半活性SHPo表面。这些进展为现实世界的实施扫清了主要障碍。
Gas-trapping-typically superhydrophobic (SHPo)-surfaces are useful for underwater applications only while their plastron lasts. Because the plastron unfortunately disappears under most practical conditions, various active approaches to supply ample gas have been reported, including the semiactive SHPo surface based on self-regulated electrolysis. Here, we report two major advances: (i) a self-powered plastron restoration mechanism that obviates the need for external power; (ii) a one-step molding process to mass-manufacture semiactive SHPo surfaces. The advances clear major hurdles for real-world implementation.
