Claim:
1. A method for preparing an organic film at the surface of a solid support, wherein it includes a step of contacting said surface with a liquid solution including: at least one aprotic solvent, at least one cleavable aryl salt and at least one radically polymerisable monomer different from said cleavable aryl salt, said organic film being polymeric or copolymeric and having a monomer unit sequence in which the first unit is constituted by a derivative of the cleavable aryl salt and the other units are derived from said cleavable aryl salt and from polymerizable monomers, wherein said contacting is under non-electrochemical conditions enabling formation of radical entities based on the cleavable aryl salt, wherein the cleavable aryl salts generate said radical entities without reacting with the surface on which said radical entities are intended to be grafted.
