Polymer brushes for silicon nitride-steel contacts: a colloidal force microscopy study
A greener lubrication solution based on self-assembling methods for steel on silicon nitride hybrid contacts is investigated in this study. Surface initiated atom transfer radical polymerisation (ATRP) is employed to produce oleophilic polymer brushes based on methyl methacrylate (MMA). This paper presents the synthesis and characteristics of poly(MMA) brushes that have been designed to synergize with a PAO lubricant whilst forming a strong covalent bond with the silicon nitride surface. By utilising activators regenerated by electron transfer (ARGET) the amount of catalyst needed is reduced to ppm levels allowing polymerisations to take place in a limited amount of air. The initiators and the polymer brushes formed on silicon nitride surfaces are characterised using XPS, contact angle, gel permeation chromatography and atomic force microscopy. The lubricating effects of the polymer brushes under dry and swollen states are evaluated using lateral force microscopy with a steel colloid.

Abstract
A greener lubrication solution based on self-assembling methods for steel on silicon nitride hybrid contacts is investigated in this study. Surface initiated atom transfer radical polymerisation (ATRP) is employed to produce oleophilic polymer brushes based on methyl methacrylate (MMA). This paper presents the synthesis and characteristics of poly(MMA) brushes that have been designed to synergize with a PAO lubricant whilst forming a strong covalent bond with the silicon nitride surface. By utilising activators regenerated by electron transfer (ARGET) the amount of catalyst needed is reduced to ppm levels allowing polymerisations to take place in a limited amount of air. The initiators and the polymer brushes formed on silicon nitride surfaces are characterised using XPS, contact angle, gel permeation chromatography and atomic force microscopy. The lubricating effects of the polymer brushes under dry and swollen states are evaluated using lateral force microscopy with a steel colloid.
