Abstract
Herein are disclosed devices, particularly medical devices, more particularly implantable medical devices, comprising a first layer of a metal and a short chain silicone terminating with silicon hydride, and a second layer of a silicone polymer. The short chain silicone is bound to the metal, and the silicone polymer is covalently bound via the vinyl group to the silicon hydride group of the short chain silicone. Also disclosed herein is a method for making such devices, involving providing the metal, depositing the short chain silicone, molding the silicone polymer as a silicone prepolymer, and polymerizing the silicone prepolymer to yield silicone polymer covalently bonded to the short chain silicone.
