Effect of biphilic pattern type, size and wettability ratio on atmospheric water collection

= 15 °C), biphilic surfaces with parallel stripes (width: 1000 μm, spacing: 2000 μm), which act as "water guides" driven by gravity and low surface coverage (35%), exhibit increased WCR by 156% compared to flat PDMS. From the fabrication point of view, the method presented here is PFAS-free and scalable, providing another pathway for the realization of water collection interfaces.
