Abstract (en)

[origin: WO2012007671A1] The invention relates to a method for grafting monomers (M) into a layer located deep inside an organic material by means of an ion beam (X), wherein: the dose of ions per unit of area is selected from a range of 1012 ions/cm2 to 1018 ions/cm2 so as to create a store of free radicals (1) in a large layer of between 0 and 3000 nm; and free radicals (1) of hydrophilic and/or hydrophobic and/or antibacterial monomers (M) are grafted into said store. Organic materials having water-repellant, hydrophilic, and/or antibacterial properties that are effective over a long period of time can thus be obtained.
