Polyesters
Polyesters (PEs) represent an important class of thermoplastic polymer materials that are well established for a wide range of applications. Being condensation polymers, they are the best recyclable polymers, with the PET material stream as most prominent example. Others, such as PCL, PLA or PBS are biocompatible and even -degradable, thus meeting more advanced requirements. Based on physically informed basic research, including state-of-the-art characterization techniques, we broaden the application range of existing polyesters via better understanding and control of their (often semi-crystalline) morphology, and develop new polyester materials as well as new pathways for (bio)degradation and re-use.
