Swelling of a polymer brush probed with a quartz crystal resonator
Abstract
We have studied the temperature dependence of swelling of a polystyrene brush in cyclohexane with quartz resonators and ellipsometry. The swelling of the layer, which has been covalently bound to a silicon oxide surface, continuously increases as the temperature is raised. The data from the quartz resonator display a ``film resonance,'' which indicates that the thickness of the brush is on the order of the wavelength of transverse sound. The quantitative analysis shows that the acoustic thickness as determined with the quartz resonator is higher than the optical thickness from ellipsometry. We argue that this difference is partly due to the high contrast achieved in acoustical measurements, which makes the quartz resonator most sensitive to dilute regions in the tail of the segment density profile. The relation between the acoustic thickness and the hydrodynamic thickness is discussed.

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.
