Abstract: A method for protecting a substrate from corrosion, which method comprises in sequence: a first step including plasma polymerization of a precursor monomer and deposition of the resultant polymer onto at least one surface of a substrate; a second step including exposing the polymer to an inert gas in the presence of a plasma without further deposition of polymer onto the or each surface of the substrate; a third step including plasma polymerization of the precursor monomer used in the first step and deposition of the resultant polymer onto the polymer deposited in the first step so as to increase the thickness of the polymer; and optionally, a fourth step including exposing the polymer to an inert gas in the presence of a plasma without further deposition of polymer onto the or each surface of the substrate.

Abstract: A plasma polymerisation method for coating a substrate with a polymer layer, which method includes: providing a substrate to be coated within a plasma chamber; introducing a flow of a first polymer precursor to the plasma chamber; applying a power at a level greater than zero Watts (W) and converting the first polymer precursor to a first polymer precursor plasma; exposing the substrate to the first polymer precursor plasma; introducing a flow of a second polymer precursor to the plasma chamber; applying a power at a level greater than zero Watts (W) and converting the second polymer precursor to a second polymer precursor plasma; and exposing the substrate to the second polymer precursor plasma, wherein exposing the substrate to the first polymer precursor plasma forms a first polymer layer thereon and exposing the substrate to the second polymer precursor plasma forms a second polymer layer thereon, characterised by maintaining the power at a level greater than zero Watts (W) between exposing the substrate

Abstract: The present invention relates to hydrophilic, multi-functional ultra-thin coatings deposited onto substrates for different applications, with excellent performance in terms of stability and durability. The present invention also describes improved methods to deposit the hydrophilic, multi-functional ultra-thin coatings of the present invention. The coatings are deposited by means of a low pressure and low power plasma polymerization. The present invention also comprises substrates coated with a method and a coating according as described in the present invention.
