Abstract: In recent years, significant advances have been made in treating surfaces to enhance their biocompatibility. This has generally involved the chemical attachmet of very thin molecular coatings to a substrate. Because failure of coated surfaces occurs often, an investigation of the stability of one such molecular coating was undertaken. The specific system studied is a polytetrafluoroethylene polymer (Teflon) with organic macromolecules of heparin ionically bonded to the polymer through use of an intermediate bo…
