How to measure swelling of thin films with QCM-D

The ability to take up and release water is central for many materials, such as hydrogels, whose function depend on the ability to hydrate and dehydrate. Hydration and swelling are also central when dealing with hygroscopic materials. QCM-D can be used to characterize such swelling phenomenon.

How to characterize viscoelastic properties with QCM-D

Wood, ice and the disks in a human spine are all viscoelastic materials. Viscoelasticity is a quality involving both viscous and elastic properties at the same time. QCM-D is a surface sensitive technology that can characterize the viscoelastic properties of thin films.

How to measure thin film degradation with QCM-D

Thin film degradation is sometimes wanted and sometimes not. In both cases, it can be important to characterize so that it can be optimized and controlled.

What can QCM-D technology be used for?

Surfaces are all around us. To control the macroscale we need to understand and tune the nanoscale. To our aid, we use analytical tools, such as QCM-D

What is the difference between QCM-D and traditional QCM?

The QCM with an added D measures an additional parameter, the dissipation factor. The QCM-D provides more information about the system under study than traditional QCM.

Characterization of Environmentally Responsive Polymers

Thanks to the complementary information combinatorial QCM-D and ellipsometry can provide, these two allow one to simultaneously monitor both polymer brush swelling and deswelling behavior, as well as attachment and detachment of protein.
