NeverWet™ coatings are a featured product at the DaVinci Inventor Showcase 2011
NeverWet™ coatings are Superhydrophobic and Oleophobic. Water on NeverWet™ surfaces sits as an almost perfect sphere. Water beads “glide” over the surfaces like a skate gliding over ice, with almost no surface friction. Superhydrophobic surfaces such as the leaves of the lotus plant have surfaces that are highly hydrophobic, i.e., extremely difficult to wet. “Oleophobic” (from the Greek (oleo) “oil”) refers to the physical property of a molecule that is repelled from oil.
The contact angle of a water on a surface is the angle of the leading edge of a water droplet on the surface as measured from the center of the droplet. A surface with a contact angle of 180 degrees would mean that water sits on it as a perfect sphere. A surface with a contact angle of 0 degrees would mean that the drop of water completely spreads and is laying completely flat on the surface.
The contact angles of a Superhydrophobic surface is where the water droplet exceeds 150° and the roll-off angle is less than 10°. This is also referred to as the Lotus effect. Here are the contact angles of water on various surfaces:
- NeverWet™ Coatings: 160 to 175 degrees
- Teflon (cooking pan): 110 degrees
- Rain-X: 95 degrees
- Freshly waxed car: 90 degrees
Key Characteristics of the NeverWet Technology are: Self-Cleaning, Anti-Wetting, Anti-Corrosion, Anti-Icing, Anti-Bacterial and Durable.
Ross Nanotechnology specializes in making extremely hydrophobic surfaces practical. Their spray on coatings are superhydrophobic and very durable. Our thin films are extremely hydrophobic and indestructable. NeverWet surfaces provide significant engineering advantages and provide a significant WOW factor when demonstrated.
