Chemical-Physical Interfaces

In our application-oriented, interdisciplinary basic research, we develop new functional polymer materials from bio-based, synthetic and bioinspired polymers, for example, to formulate active ingredients and new biomaterials for contacting biological systems. Controlled crosslinking of synthetic or natural molecular building blocks provides the hydrogels with tunable properties and biological properties associated with (bio)inks for additive manufacturing processes that are required for the construction of artificial articular cartilage or bone.

We adapt properties of material surfaces that come in contact with solid / liquid / gaseous media. Among other things, we use plasma technology in which surface changes via physical and chemical interactions are achieved by means of electrical discharges.
