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… Expand

An important application of quartz crystal resonators is the quartz crystal microbalance (QCM). It is well established as thickness monitor in vacuum deposition units or as chemical sensor, e.g., inExpand
Membrane-enhanced surface acoustic wave analysis of grafted polymer brushes.
TLDR
Detailed multilayer calculations are presented for the specific case of a poly(ethylene glycol) brush swollen with water and brought into contact with an elastomeric water-permeable membrane and confirm that the method is sensitive to the properties of the brush layer in the experimentally relevant thickness regime.

High frequency rheometry of viscoelastic coatings with the quartz crystal microbalance.
TLDR
A quantitative method for using the quartz crystal microbalance (QCM) to characterize the high frequency viscoelastic response of glassy polymer coatings with thicknesses in the 5-10 μm regime was demonstrated with a model polyurethane coating. Expand

TLDR
The small-load approximation provides a unified frame for interpretation and thereby opens the way to new applications of the QCM. Expand
Simultaneous determination of density and viscosity of liquids based on quartz-crystal resonators covered with nanoporous alumina
Quartz-crystal resonators were coated with a layer of alumina nanopores in order to allow for simultaneous measurement of density and viscosity of a liquid. Whereas the motion of the liquid containedExpand
Manipulation of electroactive polymer film viscoelasticity: The roles of applied potential and frequency
TLDR
Together, selection of operating frequency, applied potential and time scale offer the prospect of manipulating film viscoelastic parameters in a controllable manner over several orders of magnitude, from “rubbery' to near “glassy' behaviour. Expand
