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 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 QCM-D?

The QCM-D, which is an extended version of the QCM, is particularly suitable for the characterization of soft layers.

What is QCM?

A Quartz Crystal Microbalance or QCM, is essentially a balance for very small masses. But why would anyone want to weigh nanogram variations of a material?
