In general, plastics are processed at way over a hundred degrees Celsius. Enzymes, by contrast, cannot usually withstand these high temperatures. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP have managed to reconcile these contradictions: They are able to embed enzymes in plastics without the enzymes losing their activity in the process. The potentials this creates are enormous.

23 percent of global energy consumption can be attributed to friction losses. Components with reduced friction therefore represent an important contribution to conserving resources and achieving climate protection targets. In the case of plastics, reduced friction can also reduce microplastics in the environment. With the development of microcapsules filled with liquid lubricants for plastics, the Potsdam Fraunhofer Institute for Applied Polymer Research IAP and the Plastics Center SKZ in Würzburg are supporting these goals. Their self-lubricating plastics achieve up to 85 percent less wear. Since March 2021, the successful research project has been continued for two years.

The idea is that private customers will, in the future, be able to produce the hydrogen they need using small wind turbines. Lightweight construction ex perts at the Fraunhofer Institute for Applied Polymer Research IAP, at BTU Cottbus and an industrial partner are now developing the key technologies re quired: small, efficient rotors and safe tanks.

"Packaging made from bio-based plastics has long been established. We are now supporting the further development of these materials for new areas of application. If in the future the market also offers plant-based materials for technically demanding tasks such as vehicle construction, the bioeconomy will take a decisive step forward," explained Uwe Feiler, Parliamentary State Secretary at the Federal Ministry of Food and Agriculture, in Potsdam today. The occasion was the handover of a grant to the Fraunhofer Institute for Applied Polymer Research IAP. The Fraunhofer IAP wants to develop a composite material that consists entirely of bio-based polylactic acid (PLA) and is significantly easier to recycle than conventional fiber composites.

Only a few atomic layers determine whether a surface is water-repellent, printable, paintable, adhesive or antibacterial. The surface of many products is therefore specifically modified. Thanks to a new X-ray photoelectron spectrometer, the Fraunhofer Institute for Applied Polymer Research IAP can now analyze surfaces even more precisely, which is helpful when developing a process or determing sources of failures. Companies and partners benefit not only from the new analytical capabilities at Fraunhofer IAP, but also from the extensive expertise in material development, which facilitates the interpretation of data and the tuning of a manufacturing process.

On January 1, 2021, the new Emmy Noether Group "Next Generation Antimicrobial Polymers" started its work at the University of Potsdam in close cooperation with the Fraunhofer Institute for Applied Polymer Research IAP. The goal is to develop antimicrobial polymers that can replace antibiotics.
