Mark Shaw, inventor and president of UltraTech International, Inc.,
recently spoke to a TED audience about his company’s newest product —
Ultra Ever Dry — a "superhydrophobic" coating that acts as a shield
against water and water-based materials. "Hydrophobic" essentially means
"water repelling."
Spraying a material with superhydrophobic nano-particles, like the ones
present in Ultra EverDry, creates a rough surface, full of tiny spaces
between particles. And these interstitial spaces, along with the
nanoparticles themselves, “reach up and grab” air particles, according
to Shaw. The coating creates an “umbrella of air” across the surface of a
material that water cannot penetrate.
