Plasma treatments in H2 and NH3 RF (13.56 MHz) glow discharges have been used for modifying the surface of PEEK-WC-PU membranes. Water contact angle (WCA) and X-Ray photoelectron spectroscopy (XPS) analyses were performed to study the compositional changes of PEEK-WC-PU membranes after grafting. Cell culture experiments with human hepatocytes clearly show that grafting N-containing groups improves the cyto-compatibility of the membranes.

Abstract
Plasma treatments in H2 and NH3 RF (13.56 MHz) glow discharges have been used for modifying the surface of PEEK-WC-PU membranes. Water contact angle (WCA) and X-Ray photoelectron spectroscopy (XPS) analyses were performed to study the compositional changes of PEEK-WC-PU membranes after grafting. Cell culture experiments with human hepatocytes clearly show that grafting N-containing groups improves the cyto-compatibility of the membranes.File in questo prodotto:
