Název v původním jazyce

Surface chemical stability of differently terminated nanocrystalline diamond films

Popis výsledku v původním jazyce

Carbon-based material such as nanocrystalline diamond (NCD) exhibits extraordinary properties suitable for biomedical applications. Here, proper diamond surface functionalization as well as its stability against sterilization methods (e.g. ultra-sonication, dry heat, autoclave, etc.) play a crucial role for such applications. This study focuses on the evaluation of surface chemical stability of H/O/F-terminated NCD films against autoclave, ultra-sonication and ethanol treatment. The NCD films were grown on silicon substrates by a microwave plasma enhanced chemical vapor deposition method. The as grown NCD films were chemically terminated with hydrogen, oxygen and fluor containing functional groups using appropriate plasma process. The H/O/F-terminated NCD films after autoclave, ultra-sonication and ethanol treatment were investigated by scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and water contact angle (WCA) measurements.n
