Boundary lubrication under water
Article Abstract:
A study shows that the frictional stress between two sliding surfaces bearing surfactant monolayers might decrease, when immersed in water, to as little as one percent or less of its value in air or oil. This is attributed to the shift of the slip plane from between the surfactant layers, to the surfactant/substrate interface, and the low friction would be due to the fluid hydration layers surrounding the polar head groups attached to the substrate.

Lubrication by charged polymers
Article Abstract:
Research has been conducted on charged polymer brushes which are attached to surfaces rubbing across the aqueous medium. The authors have demonstrated that compared to other polymer surfactants these brushes lead to superior lubrication.
