Abstract
The phenomenon of friction increase in graphenic materials during prolonged treatment in an oxygen plasma environment has been widely recognized. In this study, we report a possible oxidation state that leads to decreased friction during oxygen plasma treatment of graphenic materials through molecular simulations. We also propose a simple, clean, and efficient method to control the reverse structural evolution for controlled oxidation. Experimental applications demonstrated a 30.6 % reduction in friction and a 130.1 % increase in friction for short and long oxygen plasma treatments, respectively, compared to the initial graphenic vacancy structure. These findings contribute to an increased understanding of the response and modulation of graphenic coatings in oxygen plasma environments.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
