文摘

The nanotribological behavior of self-assembled monolayers is investigated. The latter accommodate friction throughtransient relaxation and dilatancy effects whose kinetics depends on the structure of the confined layers. Thus, themolecular ordering onto the surfaces controls the level and the stability of the friction coefficient. Moreover, thebehavior of these systems is theoretically accounted for using a model based on the kinetics of formation and ruptureof adhesive bonds between the two shearing surfaces with an additional viscous term.
