Bio-based polymers: functionalization and characterization

The global crisis of plastic pollution necessitates a fundamental shift away from the systematic use of synthetic, petroleum-derived polymers. Replacing these with bio-based and/or biodegradable alternatives is a significant scientific challenge. Unlike their synthetic counterparts, natural and bio-derived building blocks possess unique and complex features, such as high polydispersity, intrinsic chain rigidity, and high sensitivity to temperature and humidity.
Our research aims to tackle these complexities by adapting conventional characterization methods and developing new analytical frameworks. We strive to provide a deep comprehension of the macromolecular mechanisms at play, allowing for the precise control and optimization of bio-based material properties for industrial viability.
