Nanorhéologie : écoulement limite et friction à l'interface liquide-solide [pdf]

This work adresses the interplay between surface properties and the interfacial flow of simple liquids in the vicinity of solid surfaces. We have performed nanorheology experiments on various systems using a dynamic Surface Force Apparatus.
Firstly, we have shown that the intrinsic boundary condition on smooth surfaces depends on the wetting properties of the solid surfaces, but not on the liquid viscosity. We have also studied the boundary flow and interfacial friction of water on supported phospholipid layers, which are surfaces of biological interest.
Secondly, we have investigated the drainage flow of water-glycerol mixtures on superhydrophobic surfaces. We have been able to detect and measure the elastic properties of such surfaces due to the entrapped bubbles. Finally, we have shown that, contrary to conventional notions, the presence of gas pockets on a liquid-solid interface can significantly increase the interfacial friction.
