Method for preparing an organic film at the surface of solid support under non-electrochemical conditions, solid support thus obtained and preparation kit

A method for preparing an organic film at the surface of a solid support under non-electrochemical conditions, wherein it includes

• a step of contacting said surface with a liquid solution including:
• at least one protic solvent,
• at least one radically polymerisable monomer different from the cleavable aryl salt,
• at least one cleavable aryl salt, wherein said cleavable aryl salt is chosen from the group consisting of aryl diazonium salts, aryl ammonium salts, aryl phosphonium salts and aryl sulfonium salts,
• under non-electrochemical conditions enabling the formation of radical entities based on the cleavable aryl salt and where the cleavable aryl salts generate said radicals without reacting with the surface on which said radicals are intended to be grafted, to form an organic film covalently grafted on the surface of the solid support;
• and
• a step of placing the surface of the support in contact with a suspension of at least one nano-object (NB) in a suspension solvent, the film and the nano-object having a physicochemical affinity.

• a step of contacting said surface with a liquid solution including:
• at least one protic solvent,
• at least one radically polymerisable monomer different from the cleavable aryl salt wherein said radically polymerisable monomer is a molecule comprising at least one ethylenic bond,
• at least one cleavable aryl salt, wherein said cleavable aryl salt is chosen from the group consisting of aryl diazonium salts, aryl ammonium salts, aryl phosphonium salts and aryl sulfonium salts,
• under non-electrochemical conditions enabling the formation of radical entities based on the cleavable aryl salt and where the cleavable aryl salts generate said radicals without reacting with the surface on which said radicals are intended to be grafted, to form an organic film covalently grafted on the surface of the solid support;
• and
• a step of functionalising said organic film.
