Abstract:
The invention relates to a method for chemically modifying a polymer matrix through the thickness thereof, said polymer matrix being selected from among fluoropolymer matrices and aliphatic polymer matrices. The method includes at least one step consisting in irradiating the matrix with UV light having a wavelength of less than 300 nm in order to generate zones in the thickness of the matrix that have: short polymer chains formed by scission of the existing chains during the passage of the UV rays, and free radicals known as "activated zones". The invention also relates to the polymer matrix that can be chemically modified using one such method.
Abstract:
The present invention relates to a method for preparing an organic film at the surface of a solid substrate, comprising a step of contacting said surface with a liquid solution containing (i) at least one solvent, at least one adhesion primer in non-electrochemical conditions and for generating radicalar entities from the adhesion primer. The liquid solution may further include (iii) at least one monomer different from the adhesion primer and polymerisable in a radicalar manner. The present invention also relates to an electrically non-conductive solid substrate on which an organic film is grafted according to said method, and to a kit for preparing an essentially polymeric organic film at the surface of the solid substrate.
