The versatility of polyelectrolyte multilayers, PEMs, is high, which makes them interesting for e.g. biomedical applications. The functionality is largely determined by the layer properties, which needs to be understood to be tailored. Here, we show how PEMs can be characterized with QCM-D.
Polymers and polyelectrolytes of various conformations are used in many applications where there is a need to tailor the interfacial properties to promote a certain interaction with the surrounding environment. Here we show how polymer layer crosslinking and collapse can be characterized.
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.
Adsorption and desorption phenomena are important to study in e.g. surface science and bio-related applications, where molecules are interacting with surfaces.
