提出了一种新型的集成生物启发表面的模式和梯度（WPGS）的雾收集通过一种新的阳极氧化策略。本文研究了不同参数下WPGS的集水行为。定量的力分析，提供证据的基本机制，导致液滴的定向运动，这是与实验结果一致。这样的表面不仅可以有效地提高雾滴的捕获性能，由于锯齿形图案，而且还可以加速表面再生，充分利用多种驱动力的合作，导致进一步的雾收集增强。
A novel integrative bioinspired surface with wettable patterns and gradient (WPGS) is proposed for fog collection via a novel anodic oxidation strategy. We study the water collection behaviors on WPGS with different parameters. Quantitative force analysis is presented, providing evidence for the underlying mechanism leading to the directional motion of the droplet, which is consistent with the experimental results. Such a surface can not only improve the fog droplet capture performance effectively owing to wettable patterns but also accelerate surface regeneration by taking full advantage of the cooperation of multidriving forces, leading to a further fog collection enhancement.
