Stay Superdry With Nokia's Nanotech Phone Coating



Nokia Conversations has taken some time to check out the amazing work being done at Nokia Research Center in Cambridge, UK:

Chris Bower produces two hand-held Nokia maze tiles to demonstrate the difference. First he drops water on a surface that has no coating at all: “The water spreads, like this, and coats the surface,” he says.

Trying the maze with the Superhydrophobic coating makes a dramatic difference:  the water drops and almost bounces up again, beading tightly together – and then almost skids over the surface.

Bower explains: “A hydrophobic coating – like Teflon – has a low surface energy and a high contact angle of 120 deg, which makes water form discrete droplets on the surface.”

He goes on to explain that Superhydrophobic coatings have a contact angle that can approach 180 degrees – and the liquid forms discrete drops that literally bounce off the surface:

“The difference is the nano-structured coating, trapping air at the interface, that makes sure the liquid never actually touches the surface.”
