Inspired by both the water collection strategy of desert beetles and the lubrication effect of pitcher plants, a new flexible functional surface for water collection is designed and can be easily fabricated. Such a functional surface consists mainly of a superhydrophobic region and a hydrophobic region with infused lubricating oil. Different functional patterns can be easily manipulated by different templates. Due to the flexibility of the surface, not only a two-dimensional surface but also a three-dimensional one can be designed. Directional water collection can be achieved. Furthermore, it is an integrative bioinspired functional surface that does not require any tailoring. Compared with existing functional surfaces, the present surface has higher water collection efficiency in fog and such a function can last 15 days. The functional degraded surfaces can also be easily reused.
受沙漠甲虫的集水策略和猪笼草的润滑效果启发，设计了一种新型的用于集水的柔性功能表面，且该表面易于制造。这种功能表面主要由一个超疏水区域和一个注入润滑油的疏水区域组成。不同的功能图案可以通过不同的模板轻松操控。由于表面的柔性，不仅可以设计二维表面，还可以设计三维表面。可以实现定向集水。此外，这是一种无需任何剪裁的一体化仿生功能表面。与现有的功能表面相比，该表面在雾气中具有更高的集水效率，且这种功能可持续15天。功能退化的表面也可以轻松重复使用。
