Abstract
The invention relates to the deposition or attachment of materials to surfaces. It relates to a process for coating a surface with a first material and a second material, comprising the following steps: placing the first material on the said surface, inserting into the first material placed on the said surface precursor molecules of the second material, converting the said precursor molecules of the second material inserted into the first material into the said second material such that this second material becomes formed on the said surface to be coated and within the said first material placed on the said surface. The object of the process of the invention is to allow the deposition of materials of any type onto surfaces of any type.
Claims12
A process for coating an electrically conductive or semiconductive surface, comprising:
- applying a solution of at least one monomer and an electrochemically reducible metal ion to a surface portion of the substrate to be coated;
- applying voltammetric sweeps on the coated electrically conductive or semi-conductive surface;
- wherein
- the current applied during the voltammetric sweeps simultaneously:
- a) electrografts a portion of the at least one monomer to the electrically conductive surface and a polymer chain is formed beginning with the electrografted monomers, and
- b) reduces the metal ion to metal;
- to obtain a coating comprising an electrografted polymer and a uniform distribution of metal.
