Tribological application of molecular deposition (MD) films

In this paper, the nanofriction and nanolubrication behaviors of different MD films on the Au substrate were systematically studied. The experimental results indicated that the MD films presented similar nanofriction properties when they had a same terminal. It was also found that the process of the anionning and the depositing of a monolayer MD film on a Au substrate and the process of decorating an alkyl-terminal to MD film surfaces were all capable of lowering the frictional force and improving the nanolubrication property. Moreover, the MD film decorated with alkyl chains had lower frictional forces than the undecorated MD films. Accordingly, it provided us a significant thought to seek for a new nanolubrication film.
