A method of bonding polymeric materials, in particular, polymeric materials comprising silicone, is provided along with medical devices comprising materials bonded together by said method. More specifically, the method of the present invention involves surface treating the surface of a polymeric material, preferably a polymeric material comprising silicone, such that the character of the surface of the material changes in a manner such that bondability of the material is enhanced. The surface of the surface treated polymeric material is then brought into contact with the surface of a second polymeric material and optionally, an adhesive, under conditions effective to bond the surfaces together. The bond so formed is stronger than a corresponding bond between untreated polymeric materials.
L'invention porte sur un procédé de liaison de matières polymères, notamment des matières polymères comprenant du silicone, sur des dispositifs médicaux comprenant des matières liées entre elles selon ledit procédé. L'invention concerne, plus spécifiquement, le traitement superficiel de la surface d'une matière polymère, de préférence une matière polymère comprenant du silicone, de sorte que le caractère de la surface de la matière change et que son aptitude à la liaison soit accrue. La surface de la matière polymère traitée en surface est ensuite mise en contact avec la surface d'une deuxième matière polymère et éventuellement, un adhésif, dans des conditions efficaces pour que les surfaces se lient entre elles. La liaison ainsi formée est plus forte qu'une liaison entre des matières polymères non traitées.
