| Abstract: A surface force apparatus has been used to investigate the drainage of a viscosity improver lubricant. The characterization of the VI confined interface has been performed. Surprisingly, dynamical measurements enlighten a significant negative value of the immobile layer thickness. This result is discussed in terms of occurrence of slip at the wall, liquid-solid interface wettability, surface roughness and cleanliness, and friction experiments. Consequently, an interface molecular organization modelling is proposed based on polymer depletion near the solid-liquid interface. |

| Title: Squeeze Film Lubrication in Silicone Oil: Experimental Test of the No-Slip Boundary Condition at Solid-Liquid Interfaces |

| Abstract: The hydrodynamic force between a spherical glass particle (radius similar to 10 mu m) and a smooth, flat glass plate in Newtonian silicone oil (viscosity, eta similar to 95 mPa s) was measured using the atomic force microscopy (AFM) colloidal probe technique and was compared to Reynolds lubrication theory. When the particle and plate were coated with a hydrophobic silane, the measured forces were consistent with Reynolds lubrication theory without the need to introduce the concept of a slip length. When the particle was hydrophilic, the results were more variable, sometimes being consistent with the no-slip boundary condition and sometimes being better fitted by invoking a constant slip length (up to 33 nm). The hydrophilic system was not well characterized because the hydrophilic solid may have entrained or attracted a layer of water (eta = 0.001 Pa s) of unknown thickness, which would lubricate the flow and explain the apparent slip length. In addition, all AFM force measu! rements suffer from the problem that the solids occasionally have rough patches, steps, or attached nanoparticles, which will affect the force and may cause departure from a theory that does not account for their presence. We conclude that the no-slip boundary condition is valid for solid-liquid interfaces but that some experiments entail conditions, for example, surface roughness or lubricating layers, that may give the appearance of violating the no-slip boundary condition. |
