“…6 Some oxygen components also can be found on the surface of N 2 plasma-treated polystyrene, probably created by oxygen residue in the reactor reacting with the surface during plasma treatment or by atmospheric postoxidation. 5,6 Decomposition of the high-resolution N 1s peak was not investigated because of the poor sensitivity of the nitrogen peak.…”

“…1 According to previous studies, both nitrogen-and oxygen-containing plasmas can improve the wettability, printability and biocompatibility of polymer surfaces. 2 -4 Nitrogen-containing plasmas can introduce nitrogen functions such as amine, 5 mostly primary amine NH 2 , imine (CH NH), cyano (-CN) and nitrile. 6 On the other hand, oxygen-containing plasmas are generally employed to degrade the surface of polymers, 7 although they can also cause surface functionalization due to the incorporation of oxygen-containing components such as C-O, C O, O-C O and O C-OO onto the surface.…”

The choice of plasma gas can determine the interaction between material and plasma and therefore the applications of the treated materials. Nitrogen plasma can integrate functional groups such as primary amines and carbon dioxide plasma can incorporate carboxylic groups on the surface of polymers. For specific adhesion such as bio-adhesion, polar groups must be attached to the surface to enhance bio-film formation but the acidic or basic character also controls the adhesion mechanism.Nitrogen and carbon dioxide plasmas are chosen to treat the surface of polystyrene and to show the effects of different functionalizations, i.e. attachment of acid or basic groups and degradation are compared in the present work.Nitrogen-containing plasma induces mainly weak degradation at a rate of ∼0.13 µg cm −2 s −1 . The roughness of the treated surface remains mostly unchanged. Functionalization leads to amino group attachment at a concentration of 1.2 sites nm −2 . We found that carbon dioxide plasma treatment shows more drastic degradation with a rate three times higher than that of nitrogen plasma and can create more functional groups (4.5 sites nm −2 ) at mild plasma treatment. However, the roughness of the surface is altered. In both cases the aromatic groups are degraded through the plasma treatment (again this is more evident with the CO 2 plasma) and the induced functionalization was shown to be quick (the upper monolayer of polystyrene film can be functionalized rapidly).

Timeof-flight secondary ion mass spectrometry (ToF-SIMS) is used to monitor in a semi-quantitative way the chemical modifications produced at low-density polyethylene (LDPE) film surfaces by SF, and SF,-CF, plasma treatments. The influence of the plasma treatment time (SF, plasma) and the gas composition (SF6-CF, plasma) have been investigated. The ToF-SIMS results are compared with plasma diagnostics (mass spectrometry and optical emission spectroscopy) and with some earlier XPS characterization.The ToF-SIMS study of SF, plasma-treated LDPE films as a function of the treatment time shows two different structural developments. Beside the expected formation of C,F, structures due to the grafting of F atoms, ToFSIMS detects the presence of SF, species at the surface. Their high sensitivity to ablation, due to the plasma ions, was related to two possible interactions of plasma species with the LDPE surface: an adsorption of SF:/-ions or a dissociative chemisorption of SF, neutral species. In the latter case, the low binding energy of the S-C bond can explain the high sensitivity to ablation.In the case of SF,-CF, plasma treatment, the incorporation of fluorine, as seen by ToF-SIMS, is a function of the gas composition. Two maxima are observed when the second gas (either SF, or CF,) is introduced at low concentration (-10%). These maxima are confirmed by XPS and actinometric results and are explained with respect to the reciprocal influence of both gases in the plasma discharge.
