Surface functionalisation method
The invention relates to a method for functionalising a surface of a solid substrate with at least one acrylic acid polymer layer, said method including the steps of: i) placing the surface in contact with a solution having of at least one acrylic acid homopolymer, a solvent and, optionally, metal salts; ii) removing the solvent from the solution in contact with the surface; and iii) binding the polymer to the surface by thermal treatment.
1. A process for functionalizing a surface of a solid support with at least one layer of polymer of acrylic acid, said process comprising the stages of:
i) bringing said surface into contact with a solution consisting of:
at least one acrylic acid homopolymer; and
a solvent;
ii) removing the solvent from the solution in contact with said surface; and
iii) fixing the polymer to said surface by heat treatment at a temperature of between 150° C. and 300° C.;
the solid support being selected from the group consisting of metal oxides, papers, and carbon fibers.
2. The process as claimed in claim 1 , in which the polymer is applied to the surface of the solid support by dipping, centrifuging, sprinkling, projection or transfer.
3. The process as claimed in claim 1 , in which the process additionally comprises stages ii 1 ) and ii 2 ), subsequent to stage ii) of:
ii 1 ) rinsing the surface of the solid support obtained in stage ii) with water; and
ii 2 ) drying said surface.
4. The process as claimed in claim 1 , comprising a stage, subsequent to stage iii), of covalent grafting of at least one molecule to the polymer layer obtained.
5. The process as claimed in claim 4 , in which the at least one molecule is a biological molecule or a resin.
6. The process as claimed in claim 4 , in which the at least one molecule consists of two molecules as a two-component resin.
7. The process as claimed in claim 1 , wherein the support comprises metal oxides.
8. The process as claimed in claim 1 , wherein the support is selected from the group consisting of papers and carbon fibers.
9. The process as claimed in claim 1 , wherein the support comprises papers.
