Thin Film Rheology and Tribology of Confined Polymer Melts: Contrasts with Bulk Properties
Abstract
A modified Surface Forces Apparatus was used for making rheological and tribological measurements of thin fluid films, and polybutadiene (PBD) of M w ≈ 7000 was studied in detail. At low shear rates, PBD exhibits bulklike properties in films thicker than about 200 nm. In thinner films (200−20 nm), the shear viscosity η eff and moduli G ‘ and G ‘‘ become quantitatively modified from those of the bulk. However, a sinusoidal input still produces a sinusoidal output, and a modified WLF representation remains applicable to such films. On entering the tribological regime (film thickness <30 nm) polybutadiene exhibits highly nonlinear behavior and yield points, indicative of phase transitions to “glassy” or “solidlike” states. Other features are (i) a shift of the slip plane, (ii) an additional normal force component, and (iii) the emergence of new scaling relationships for η eff, G ‘, G ‘‘, and the friction force F as a function of frequency, sliding speed, and other system parameters.

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.
