Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting
Researchers have developed a topography‑free slippery liquid‑infused porous surface (HOIPS) that uses spatially patterned dual lubricants to create interfacial energy contrasts, directing droplet migration without external forces. By chemically fluorinating selected regions of a PTMSDPA polymer film and infusing fluorinated oil and silicone oil into their respective domains, droplets condense on fluorinated zones and migrate to silicone‑oil zones where they coalesce rapidly. The ultrathin (~200 nm) flexible coating works on flat, curved, and flexible substrates, achieving up to 2.5‑fold higher water‑harvesting efficiency compared with traditional single‑lubricant SLIPS. Real‑time fluorescence of the polymer enables dye‑free visualization of lubricant distribution.
