Nitrogen plasma treatments that modify polymer surfaces are often accompanied by uncontrollable oxidation phenomena. Air exposure of the treated samples after the plasma process may be the origin of the oxidation, but other oxygen contamination sources during the plasma treatment procedure cannot be eliminated. To clarify this point, nitrogen plasma treatments of polypropylene are carried out in a reactor that is coupled directly to an XPS spectrometer. This avoids any air transfer of the polymer between its plasma treatment and its surface characterization. The results indicate a certain level of oxygen incorporation in the polymer during the plasma process, probably by species coming from the reactor wall. Copyright © 2000 John Wiley & Sons, Ltd.
