Atomic force microscopy study of contamination process of glass surface exposed to oleic acid vapors

Abstract

In this study, we exposed glass substrates to acid oleic vapor (vapor pressure 9 × 10-5 Torr at 78 °C) for different periods of time (10-60 min). Before the exposure to oleic acid vapor, the glass substrates were cleaned and hydroxylated by low-pressure water vapor plasma. The contaminated surfaces were examined by atomic force microscopy, which revealed formation and growing of oleic acid nanodroplets on glass surfaces.
