This work focuses on aging of surface terminated NCD and DLC films studied by XPS, WCA and SEM. The initial surface terminations were done by RF plasma in appropriate gas mixtures.The XPS and WCA measurements of O-NCD and O-DLC films showed increase of oxygen content (up to 8at.%) when WCA was <10°. The hydrogen termination caused decline of oxygen (~3at.%) and increase of WCA (>70°) for both materials. Aged H-NCD and H-DLC films showed constant oxygen concentration (~4at.%) whereas oxidized samples had degraded. The XPS revealed two times higher amount of nitrogen on DLC films rather than on diamond. Although nitrogen content of both aged samples is sufficient for further bioapplications.Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2018
