Mool Gupta from the University of Virginia presents a project supported by NSF under the PF Air program, focusing on commercializing a water-repelling technology. The demonstration shows how textured aluminum surfaces repel water, unlike regular aluminum. This super hydrophobic property can be replicated on polymeric surfaces, offering a low-cost solution with similar water-repelling properties. These textured surfaces can be applied to metals and polymers, providing benefits like corrosion protection and resistance.
