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.
