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.

Polymer coatings and methods for depositing polymer coatings

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.

Hydrophilic, multifunctional ultra-thin coatings with excellent stability and durability

A method is provided for at least partially preventing discolouration of a substrate by a plasma coating process, by diffusing a plasma prior to and/or during depositing of said plasma on said substrate to form a coating. Also provided is a plasma coating apparatus comprising a plasma diffuser for homogenizing a plasma density nearby a substrate to be coated.

Plasma diffuser method and apparatus

The present invention concerns a method comprising the steps of: introducing a substrate comprising a surface to be coated in a low-pressure reaction chamber; exposing said surface to a plasma during a treatment period within said reaction chamber; ensuring a stable plasma ignition by applying a power input, characterized in that the power input is continuously strictly higher than zero Watt (W) during said treatment period and comprises at least a lower limit power and at least an upper limit power strictly larger than said lower limit power, thereby obtaining a substrate with a coated surface. The present invention further concerns an apparatus for treating a substrate with a low-pressure plasma process and a substrate treated as such.

Ways to generate plasma in continuous power mode for low pressure plasma processes

The present invention provides a method for applying a surface coating on, for example, a sheet of fabric and further provides a plasma chamber () for coating a sheet of fabric, e.g. a textile material, with a polymer layer, the plasma chamber () comprising a plurality of electrode layers (RF, M) arranged successively within the plasma chamber, wherein at least two adjacent electrode layers are radiofrequency electrode layers (RF) or ground electrode layers (M), thereby providing a surface coating on both sides of a fabric sheet.

Apparatus and method for applying surface coatings

The invention provides a method of coating a fabric, e.g. a textile material, with a polymer coating, which method comprises contacting a fabric with a monomer and subjecting the monomer to low power plasma polymerization, wherein the monomer comprises the general formula (I): CFCXCRY&#x2014;OCO&#x2014;C(R)&#x2550;CH, wherein n is 2 to 6, m is 0 to 9, X and Y are H, F, Cl, Br or I, Ris H or alkyl, e.g. &#x2014;CH, or a substituted alkyl, e.g. an at least partially halo-substituted alkyl, and Ris H or alkyl, e.g. &#x2014;CHor a substituted alkyl, e.g. an at least partially halo-substituted alkyl.
