主 题：Friction Ice-like water MoO_(3) Graphite
摘 要：How water layer adsorbed on solid surface under ambient conditions affects the interfacial friction is a fundamental question for understanding the friction and lubrication phenomena in practical *** investigate the formation of ice-like(IL)water layers on the hydrophobic surface of graphite with partially covered MoO_(3)nanoflakes(NFs)using atomic force microscopy(AFM)based *** IL water layers are found surrounding the MoO_(3)NFs and also intercalated at the MoO_(3)/graphite interface,as proved by thickness measurements as well as local adhesion force and surface potential *** manipulations carried out on MoO_(3)NFs on graphite show that the presence of the IL water layers increases the frictional resistance of the *** the results on continuous and discontinuous IL water layers,we can identify the different sliding interfaces in the two *** increased friction for MoO_(3)NFs sliding on graphite with an intercalated water layer is attributed to the energy dissipation originated from the metastable nature of the IL layers.
