Abstract

The antiwear properties of amphiphilic monolayers and composite multilayer on silicon surface were investigated using micro­tribometer and Auger Electron Spectroscopy. Langmuir­Blodgett (LB) monolayers from behenic acid, 2,4­heneicosanedione(HD) and its lopper complex((HD)$_2$Cu) were fabricated on silicon surface and the composite multilayer of 5­bilayer of (HD)$_2$Cu was fabricated on the surface of octadecyltrichlorosilane (OTS) self­assembled monolayer (SAM). We observed that LB monolayers and the composite multilayer exhibited a steady and excellent friction response when compared with the OTS SAM. These LB mono and multilayer also showed much higher wear­resistance than the OTS SAM.
