RÉSUMÉ: La présente étude a été conçue en vue de déterminer si une modification de la surface par PICVD (dépôt chimique en phase vapeur photo-initié) a une incidence différente sur les propriétés physicochimiques du polyéthylèneglycol (PEG) que sur celles du polyvinylalcool (PVA), étant donné leur structure et leurs propriétés chimiques différentes. Les mesures de l'angle de contact ont révélé une augmentation de l'hydrophobicité de la surface des deux polymères après un traitement par PICVD. De plus, l'accroissement de l'hydrophobicité a facilité la dispersion dans les solvants non polaires. Les changements chimiques étaient concentrés près de la surface, comme en témoignent les mesures de spectroscopie infrarouge à transformée de Fourier ...
