Dispersibility and rheological behavior of functionalized silica nanoparticles as lubricant additives

Silica nanoparticles exhibited excellent tribological properties when used as lubricant additives, but the bad dispersity in lubricant limited their application. Also, the influence of nanoparticles on lubricant rheological properties was still unclear. In this paper, hairy silica nanoparticles with different functional groups and different diameters were prepared and tested with their dispersity and rheological behavior as additives to...
