Abstract
A method for the volumetric inclusion and grafting of hydrophilic compounds in a hydrophobic substrate, comprising the steps of immersing said hydrophobic polymerized substrate in a solution containing hydrophilic monomers in the presence of at least one polymerization inhibitor, and irradiating said solution by means of an ionizing radiation, in order to graft and polymerize the hydrophilic inclusions generated by the hydrophilic monomers in said substrate.
