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.
本文提出了一种新颖的基于整体仿生的浸润图案和梯度表面（WPGS），通过一种新颖的阳极氧化策略来实现雾的收集。我们研究了不同参数下 WPGS 的水收集行为。提出了定量力分析，为导致液滴定向运动的潜在机制提供了证据，这与实验结果一致。这种表面不仅可以通过浸润图案有效提高雾滴的捕获性能，而且可以充分利用多驱动力的协同作用加速表面再生，从而进一步提高雾的收集效率。
