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.
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.
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.
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.
Combining QCM-D and spectroscopic ellipsometry in one measurement. This allows for data to be recorded simultaneously with both techniques on the same surface.
