METHOD FOR CHEMICALLY MODIFYING A POLYMER MATRIX THROUGH THE THICKNESS THEREOF

摘要

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.
