This invention relates to a method for preparing an organic film at the surface of a solid support, with a step of contacting the surface with a liquid solution including (i) at least one protic solvent, (ii) at least one adhesion primer, and (iii) at least one monomer different from the adhesion primer and radically polymerisable, under non-electrochemical conditions, and allowing the formation of radical entities based on the adhesion primer. This invention also relates to a non-electrically-conductive solid support on which an organic film is grafted, and a kit for preparing an essentially polymeric organic film at the surface of a solid support.

The present invention relates to a coating method by electrocatalyzed chemical grafting of a surface of a substrate with a polymeric layer characterized in that it comprises the following steps: The invention also relates to a substrate obtained according to the coating method by electrocatalyzed chemical grafting, the surface of which is coated with a polymeric layer.

Coating method by electrocatalyzed chemical grafting of a surface of a substrate with a polymeric layer

The present invention relates to a process for coating a surface of a substrate made of nonmetallic material with a metal layer consisting of providing a substrate made of nonmetallic material; subjecting a surface of said substrate to a treatment for increasing the specific surface area thereof; subjecting the resulting surface to an oxidizing treatment; contacting the resulting substrate with a solution containing an ion of a metal from groups IB and VIII of the Periodic Table; obtaining a substrate comprising ions of a metal that are chemically attached to the nonmetallic material constituting the substrate on at least one of its surfaces; subjecting the ions to a reducing treatment to obtain a substrate comprising atoms of a metal that are chemically attached to the nonmetallic material constituting the substrate on a part of at least one of its surfaces; and contacting the resulting surface with a solution containing ions of a metal.
