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.
