Our team is excited to share our latest work exploring more sustainable pathways in polymer science. As society continues to seek alternatives to fossil-derived materials, biodegradable and biobased polymers are more important than ever. Using small-angle X-ray scattering (SAXS) data collected at the European Synchrotron Radiation Facility (ESRF) in Grenoble, paired with TEM analysis, we systematically explored how varying the PLA weight fraction influences the self-assembly and resulting morphology of PLA–PF–PLA triblock systems. From lamellae in lower-molecular-weight materials to hexagonally packed cylinders in higher-molecular-weight analogues, we captured how subtle compositional changes drive significant structural transitions. To frame these findings within sustainable materials design, we also conducted an in-depth E-factor analysis, demonstrating how process optimization is essential as demand grows for greener, more sustainable polymers. I would like to acknowledge the invaluable guidance of my promotor Prof. dr. Louis Pitet, and co-promotor Prof. dr. Geert-Jan Graulus, as well as Sander Driesen and the rest of the AFP and BDG group throughout this study. Their scientific insight and continuous support were essential to the success of this work.
