Abstract

See full text

The invention provides a method of coating a surface with a water and oil repellant polymer layer. The method comprises the steps of providing a substrate with a surface, exposing the surface to a monomer compound, and exposing the surface to a continuous plasma having a plasma power provided by a plasma circuit. During the exposition of the surface to the continuous plasma, the plasma power is reduced from an initial higher plasma power to a final lower plasma power, the final lower plasma power being less than 35% of the initial higher plasma power, thus applying an even polymer layer exhibiting a water contact angle of more than 110°.
