Microtribological Characterization of Self Assembled and Langmuir-Blodgett Monolayers by Atomic and Friction Force Microscopy,

Abstract

Organized and dense monolayers were produced by chemical grafting of molecules and by Langmuir Blodgett (L-B) deposition. Friction, wear and indentation of these films on a microscale have been studied using atomic force microscopy friction force microscopy (AFM/FFM). For comparison, macroscale friction and wear measurements have also been made. Mechanisms of friction, wear and lubrication of chemical grafted and L-B films are discussed. These studies show that coefficient of friction, wear resistance, and nanoindentation properties of C18 double grafted films are superior to L-B films. It is concluded that chemical grafted films may be suitable for lubrication of microcomponents.
