Observations of the topography and friction properties of macromolecular thin films at the nanometer scale

摘要

The research work in this paper is on the microtribological properties of C_(60)-Pst macromolecular thin films. The C_(60)-polystyrene (C_(60)-Pst) molecule is hyperbranched. AFM/FFM techniques are used for observing the topography and friction properties of surface-modified C_(60)-Pst thin films at the nanometer scale. The synthesized product was analyzed with GPC and FTIR spectrometry. Monolayer and multilayer thin films of C_(60)-Pst macromolecules were prepared using a LB (Langmuir-Blodgett) film technique. The structural and frictional properties of these thin films were tested using AFM/FFM. The topography of the LB film surface, transference of molecules and friction of C_(60)-Pst thin films using FFM were observed.
