Improving Blood and Tissue Compatibility of Poly(Ethylene Terephthalate) by Ion Beam Treatment

Poly(ethylene terephthalate) (PET) has desirable qualities for medical application but it is a nonpolar material (γ p s = 0.6 dyn/cm) which results in its high interfacial tension with blood plasma (γSL = 50 dyn/cm). Modifications of the surface free energy components of PET by ion-beam treat ments...

Beschreibung
Zusammenfassung:	Poly(ethylene terephthalate) (PET) has desirable qualities for medical application but it is a nonpolar material (γ p s = 0.6 dyn/cm) which results in its high interfacial tension with blood plasma (γSL = 50 dyn/cm). Modifications of the surface free energy components of PET by ion-beam treat ments were investigated. Also the surface morphology of the treated PET by scanning electron microscopy was revealed. The influence of such modifications on biocompatibility of these materials was investigated by subcutaneous im plants in rats.
