Functional Polymer Systems

In the division Functional Polymer Systems, we develop polymeric materials that offer capabilities beyond those of conventional plastics, including electrical, optical, and shape memory properties. We design materials along the entire value chain, from synthesis to industrial manufacturing.

Our shape memory materials can be programmed to change their shape in a controlled manner – either permanently or reversibly, for example when triggered by heat. We develop shape memory polymers for applications such as 3D and 4D printing as well as foams. We support industrial partners in translating concepts for movable or self-adapting components into functional solutions.

In the field of organic and printed electronics, we develop systems for displays, lighting, sensors, actuators, energy harvesting, and energy storage. We have expertise in scalable synthesis processes for tailored nanomaterials, cadmium-free quantum dots, semiconducting polymers, polymer electrolytes, electroactive polymers, and color-changing systems. A key focus is on solution processing of these materials. For this purpose, we formulate inks for printing processes, in particular inkjet, EHD jet, slot-die, and blade coating.

Our work focuses on the development of ionically conductive materials used in key energy technologies such as electrolyzers, fuel cells, and batteries. We design and synthesize functional polymers that serve as membranes, solid electrolytes, or binders in electrodes. Particular emphasis is placed on the development of PFAS-free materials to provide high-performance and environmentally compatible solutions for energy conversion and storage.

We develop a range of electroactive polymers, including dielectric elastomers, piezoelectric polymers, electrets, and relaxor ferroelectric polymers. As components with thin functional layers or multilayer systems, in some cases combined with tailored flexible electrodes, these sensors and actuators are used, for example, in soft robotics, enable haptic feedback and impact detection, or serve as transducers in efficient heating and cooling systems.
