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

Mool Gupta, a researcher in the University of Virginia School of Engineering supported by the NSF Partnerships for Innovation: Accelerating Innovation Research program, is developing a low-cost, scalable process to make surfaces repel water.

Gupta uses lasers to create micro-textured patterns on the surfaces of materials to make them water repellant, or superhydrophobic. Water-repellent surfaces are much less susceptible to ice and corrosion, and so low-cost, durable superhydrophobic materials are in high demand.

Gupta demonstrates on a piece of aluminum and says the same process may be duplicated on other materials, such as low-cost polymers.

The technology could potentially mean significant cost savings for industrial manufacturing, such as aircraft, renewable energy generators, and communications.
