Dynamic Properties of Molecularly Thin Liquid Films

Israelachvili, Jacob N., McGuiggan, Patricia M., Homola, Andrew M.·1988·Science

Abstract

An experimental technique is described for simultaneously measuring the static and dynamic interactions of very thin liquid films between two surfaces as they are moved normally or laterally relative to each other. Film thickness can be measured and controlled to 1 angstrom. Initial results are presented of the transition in the physical properties of liquid films only one molecular layer thick to thicker films whose properties are practically indistinguishable from the bulk. In particular, the results show that two molecularly smooth surfaces, when close together in simple liquids, slide (shear) past each other while separated by a discrete number of molecular layers, and that the frictional force is "quantized" with the number of layers.

  • Non-associating liquids, including organic solvents and oils, become solid-like with a viscosity that diverges when confined between two surfaces as they slide past each other across films just a few monolayers thick.

    “Non-associating liquids, including organic solvents and oils, are known to become solid-like, with a viscosity which diverges, when confined between two surfaces as they slide past each other across films that are just a few monolayers thick [39, 40].”

  • For organic liquids or oils, when confined to molecularly-thin layers (in the range 5-10 molecular diameters or less) such liquids become solid-like, and their effective viscosity diverges.

    “For the case of organic liquids or oils, it has been realized for some time that when confined to molecularly-thin layers (in the range 5 -10 molecular diameters or less) such liquids become solid-like, and their effective viscosity diverges [39, 40, 52].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
