Superhydrophobic Coating

Super-Hydrophobic and Oleophobic Coating

What is Nanotechnology?

• Nanotechnology is the engineering of functional systems at the molecular scale.

What do the terms “superhydrophobic” and

“oleophobic” mean?

Super-Hydrophobic describes a coating that exhibits superior water repelling properties that exceeds 150 degrees of contact angle when measuring the sphere of a drop of water on the surface. It creates an angle of 165-175 degrees. Well-known windshield water repellents are closer to 110 degrees.

Oleophobic refers to the ability to repel oil and other hydrocarbons.

What are its composition?

• Manganese Oxide Polystyrene (MnO2/PS) nano-composite

• Zinc Oxide Polystyrene (ZnO/PS) nano-composite

• Precipitated Calcium Carbonate• Carbon nano-tube structures• Silica nano-coating 

How does it work?

It uses proprietary nanotechnology to coat an object and create a barrier on its surface. This barrier repels water, oil and other liquids unlike any coating seen before.

The coating is molecularly bound to the product surface at a nanoscopic level, which means it becomes inseparable from it and is as durable as the material it protects. Because the coating is one thousand times thinner than a human hair, it is invisible to sight or touch.

What are its features?

• Anti-Corrosion

Maximum corrosion protection since water and moisture never actually contact the base material.

• Anti-wetting

keeps objects dry, water and other liquids simply repel off.

• Anti-Icing

Keeps coated materials dry, eliminating the formation of ice.

• Anti-Contamination

Dust, dirt, water and other liquids that contain bacteria or radiation never actually contact the surface of the coated material so bacteria and radiation is greatly diminished or eliminated and easy to decontaminate to sterile, if needed.

• Product Life-Extending

Many products fail from moisture, water, oil or simply getting too dirty for continued use. Super hydrophobic coating extends the life of work gloves and other Personal Protective Equipment (PPE), electric motors by preventing moisture on the windings, coat nuts and bolts to prevent corrosion, coat tools, equipment, and virtually any item that needs to be kept dry, corrosion free, de-iced, uncontaminated or clean.

Applications and Uses

Super-hydrophobic coatings have important applications in maritime industry. They can yield skin-friction drag reduction for ships' hulls, thus increasing fuel efficiency. Such a coating should allow ships to increase their speed and range while reducing fuel costs. They can also reduce corrosion and prevent marine organisms from growing on a ship's hull.

Super-hydrophobic coatings have potential uses in vehicle windshields to prevent rain droplets from clinging to the glass.

The coatings also make removal of salt deposits possible without using fresh water.

Furthermore, super-hydrophobic coatings have the ability to harvest other minerals from seawater brine with ease.

Due to the coating's hydrophobic and self-cleaning properties, it makes it extremely difficult for a treated surface to harbor bacteria. This allows tools and surfaces to remain sterile, even after contact with contaminating fluids.

Economic Benefits

The prices for these products range from $10 to $90 per gallon, and so could save the global market $1.13 billion.

• Consumer product brands providing such surface protection include:

Super-hydrophobic coatings also last longer than traditional coatings: over a year with one application, or more with additional coats.By using Super-hydrophobic coatings, the world could save billions of dollars not only in maritime industries but also in everyday life.
