Abstract:
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.
Abstract:
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 polymerisation, wherein the monomer comprises the general formula (I): C n F 2n+1 C m X 2m CR 1 Y-OCO-C(R 2 ) = CH 2, wherein n is 2 to 6,m is 0 to 9, X and Y are H, F, Cl, Br or I, R 1 is H or alkyl, e.g. –CH 3 , or a substituted alkyl, e.g. an at least partially halo-substituted alkyl, and R 2 is H or alkyl, e.g. –CH 3 or a substituted alkyl, e.g. an at least partially halo-substituted alkyl.
Abstract:
The invention relates to a conformal nanocoating applied by a low pressure plasma process. The invention also relates to a method for making such a conformal nanocoating on a three-dimensional nanostructure, in particular a three- dimensional structure containing electrically conductive and non-conductive elements.
