Hydrophilic modification of surfaces via plasma polymerization

Presented method has therefore a good potential to become a wider platform for creating cost-effective intermediate adhesive layers. Well hydrophilic thin surfaces were obtained for treatment time of 1 second and superhydrophilic surfaces were obtained after 10 seconds of plasma treatment. Thus prepared thin layers of plasma polymer have great time stability of wettability properties, are smooth, homogenous, moderately flexible and have good adhesion to the substrate. Wettability of deposited layer was characterized using water contact angle measurement and surface free energy evaluation. The chemical composition of deposited layer was characterized by XPS spectroscopy and ATR-FTIR spectroscopy. Surface morphology was observed via SEM. (authors)
