Description
Abir Jilan, Estefania Solano-Calderon, and Shabnam Mohammadshahi measure how long the air skin of a superhydrophobic surface survives underwater. That trapped air layer, the plastron, is what lets such surfaces repel water, and its life is set by gas slowly dissolving away. Their 2025 paper prints seven micro-post textures, coats them to repel water fiercely, and sinks them in water holding different amounts of dissolved air.
Two camera views tracked the layer's decay and the moment the surface flipped from air-holding to fully wet. Life lengthened as the water held more dissolved gas, in every texture. Wider gaps between posts shortened life, taller posts lengthened it, and post thickness mattered little. Side views caught the water line unpinning in steps down the posts. A compact formula captures the pattern, giving designers numbers for building surfaces whose air skin lasts.
