Observations of the topography and friction properties of macromolecular thin films at the nanometer scale
Additional Document Info
The research work in this paper is on the microtribological properties of C60-Pst macromolecular thin films. The C60-polystyrene (C60-Pst) molecule is hyperbranched. AFM/FFM techniques are used for observing the topography and friction properties of surface-modified C60-Pst thin films at the nanometer scale. The synthesized product was analyzed with GPC and FTIR spectrometry. Monolayer and multilayer thin films of C60-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 C60-Pst thin films using FFM were observed. 2001 Elsevier Science B.V. All rights reserved.
