Inthisstudy,commercialpolyvinylchloride(PVC)filmsweretreatedbyoxygenandargonplasmasinacylindricalglasstubewhichwassurroundedbyaDCvariablemagneticfield,withdifferentsamplepositionsintheplasmareactorandalsodifferentexposuredurations.Effectsoftheplasmatreatmentonthehydrophilicpropertiesofthefilmswerestudiedbymeasuringthewaterdropcontactangleonthesurfaceofthesamples.Thesurfacetopographyoftheuntreatedandplasmatreatedfilmswasanalyzedandcomparedbyatomicforcemicroscopy(AFM).Theopticalcharacteristicchangesintreatedsampleswereinvestigatedusingreflectivespectrophotometry.Also,thechemicalchangeswhichappearedonthesurfaceofthesampleswereinvestigatedusingFouriertransforminfraredspectroscopy(FTIR).TheresultsshowthattheplasmatreatedPVCbecomesmorehydrophilicwithanenhancedwettability.Asharpdecreaseinthewatercontactanglemayalsobeaconsequenceofthesurfacetexturization.Theagingeffectonwettabilityofthesampleswasalsoinvestigated.Theresultsshowthattheeffectofoxygenplasmaonthesurfacepropertiesofthesamplesismorepronouncedcomparedwiththatofargonplasma.
