Analysis of microscopic modifications and macroscopic surface properties of polystyrene thin films treated under DC pulsed discharge conditions
Résumé
Using a DC pulsed plasma for the polymer surface treatment allows the attainment of macroscopic modifications of the surface such as an important increase of the wettability. In the same time microscopic variations of the surface structure are mainly linked to low depth chemical modifications even if very weak roughness changes appear. As a consequence this technique presents two major interests. The first one is an economical interest because of the low power consumption compared to other techniques like radiofrequency or microwaves plasmas. The second one is the very significant treatment (macroscopic) realized in soft conditions without degradation of the polymer. These results composed of macroscopic and microscopic studies on polystyrene surfaces may allow to establish a macroscopic interpretation of the interaction between polymer and the DC pulsed plasma.
