Abstract
A method for forming a coating on a substrate using an atmospheric pressure plasma discharge. The method comprises introducing an atomized liquid and/or solid coating-forming material into an atmospheric pressure plasma discharge and/or an ionized gas stream resulting therefrom, and exposing the substrate to the atomized coating-forming material. The application also described a method for polymerizing a polymer forming material, and further to apparatus for forming a coating on a substrate.
Claims21
A method for polymerizing a polymer forming material, which method comprises atomizing the polymer-forming material selected from the group consisting of:
- (i) an atomized liquid, and
- (ii) a combination of an atomized liquid and an atomized solid, exposing (i) or (ii) to a homogeneous atmospheric pressure plasma glow discharge, and exposing a substrate to (i) or (ii).
A method for co-polymerizing a liquid coating-forming monomer material under conditions of atmospheric pressure, which method comprises atomizing the liquid coating-forming monomer material, exposing the atomized liquid coating-forming monomer material to a homogeneous atmospheric pressure plasma glow discharge, and exposing a substrate to the atomized liquid coating-forming monomer material.
A method for co-polymerizing a solid coating-forming monomer material under conditions of atmospheric pressure, which method comprises atomizing the solid coating-forming monomer material, exposing the atomized solid coating-forming monomer material to a homogeneous atmospheric pressure plasma glow discharge, and exposing a substrate to the atomized solid coating-forming monomer material.
A method for forming a coating on a substrate under conditions of atmospheric pressure, the method comprising:
- (I) introducing a coating-forming material selected from the group consisting of:
- (i) an atomized liquid, and
- (ii) a combination of an atomized liquid and an atomized solid, into an atmosphere selected from:
- (a) a homogeneous atmospheric pressure plasma glow discharge and
- (b) an ionized gas stream resulting therefrom, and
- (II) exposing the substrate to (i) or (ii).
