A waterproof smartphone? Amazing spray coating makes it possible [video]

By | November 14, 2011, 6:10 AM PST

Neverwet, a new spray coating, can turn almost anything waterproof. Like seriously waterproof, as in messy sauces, juice, ink and oil don’t just bead off — they shoot off the surface. It’s also anti-corrosive, sending even bacteria and ice running and screaming for the hills.

While there are a host of water-resistant coatings and products available, most only offer hydrophobic properties and fall short of the litmus test to be considered “waterproof.” Ross Technologies claims that their silicon-based product is superhydrophobic, meaning it repels liquids at a very high “contact angle” (175 degrees), which is the distance wedged between a water droplet and the surface. So the higher the contact angle, the rounder the water droplet.

The secret to how the patent-pending technology works is a proprietary arrangement of nanoparticles that turns water droplets into near-perfect spheres. Originally, researchers at the company had set about developing a material that would prevent steel from corroding and realized that such a product might also work on a variety of surfaces, including fabrics. They eventually came up with a separate coating that can be applied just about anywhere.

To demonstrate Neverwet’s mighty water, stain and dirt-repelling abilities, the company has produced a series of mini-infomercials where spilled water scurries away in terror, chocolate syrup simply slides off a treated shoe and a coated iPhone is shown to still work while submerged underwater — even after half an hour. The company says that the coating is exceptionally durable, stating on their website that “NeverWet™ coatings have remained under seawater for over a year and reemerged completely dry.”

The final product isn’t scheduled to hit the market until sometime next year. But if it lives up to the hype, mustard stains won’t stand a chance.

What would happen
If this were used on the hull of a boat??
Would it replace wax on a car finish or gelcoat?
Fascinating!

Super-planing hulls?
Either that, or the boat will shoot straight up out of the water, fall back into the water, then shoot up again, and fall back and do this over and over again, like a ping-pong ball slammed between a paddle and the table...Wow, that would be some ride!

Dirt
So...what if you get your clothes dirty with dry dirt? How do you wash your clothes if it repels water? Just a thought...

wet the dirt?
if it was wet, maybe it would slide off suspended with the water. This requires an experiment. also what about any chemical in the dirt or otherwise that would mess up the water's surface tension?
