Stability of the surface termination of nanocrystalline diamond and diamond-like carbon films exposed to open air conditions

Popis výsledku v původním jazyce

Tailorable surface termination of NCD and DLC films significantly contribute to their wide potential applications in biomedicine which require defined and stable surface towards aging. Here, we present a comparative study on the surface termination stability of NCD and DLC films. The samples were plasma-treated with hydrogen, oxygen or nitrogen containing functional groups employing low temperature RF or high temperature MW plasma. The samples were exposed to air up to 30 days. It was shown that NCD films were more efficiently hydrogenated in the high temperature MW plasma than in RF plasma. However, the MW plasma deteriorated the surface of the DLC film. Generally, the NCD film showed more stable surface termination than DLC. The possible reasons of the different behavior of WCA and XPS results and complex characterization of H-, O- and NH2-terminated NCD and DLC film regarding to the aging and surface termination stability are discussed in the article.
