A laser-focused, scalable process to make materials repel water

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.

What are the potential applications of the low-cost replication process mentioned in the text?

Explain the significance of micro texture in the context of water repellency.
