Method of Coating a Polymer Surface with a Polymer Containing Coating and an Item Comprising a Polymer Coated Polymer
First Claim
1. A method of coating a surface of a solid polymer substrate with a coating comprising a coat polymer, said method comprising:
- providing a coat polymer for the coating, and dissolving said coat polymer in a first solvent,placing said solid polymer substrate in a reaction chamber,introducing said polymer coat solution into the reaction chamber,introducing carbon dioxide into the reaction chamber, anddepositing the coating onto the solid polymer substrate surface,wherein the carbon dioxide during at least a part of the deposition step is in its liquid state at a pressure up to 7.4 MPa.

Abstract
A method of coating a surface of a solid polymer substrate, e.g. comprising silicone, thermoplast, thermoset and/or elastomers, with a coating comprising a coat polymer.
The method includes providing a coat polymer, such as a polymer polymer comprises one or more polymer having metacrylate backbone, for the coating, and dissolving said coat polymer in a first solvent, such as water, carbon dioxide and/or organic solvents, placing said solid polymer substrate in a reaction chamber introducing said polymer coat solution into the reaction chamber, introducing carbon dioxide into the reaction chamber, and depositing the coating onto the solid polymer substrate surface, wherein the carbon dioxide during at least a part of the deposition step is in its liquid state at a pressure of 7.4 Mpa or less. Optionally the carbon dioxide is subjected to turbulence, e.g. by mechanical stirring during at least a part of the deposition step.
