Our Research

Our research focuses on the design and synthesis of sustainable semicrystalline polymers using bio-based monomers and innovative strategies. We aim to understand and control the structure-property relationships that govern polymer crystallization and performance. By integrating fundamental insights with material innovation, we contribute to the development of next-generation, environmentally responsible polymers.

Development of Sustainable Semicrystalline Polymers

Approximately 70% of commercial polymers are semicrystalline. This semicrystalline structure imparts appropriate mechanical properties and dimensional stability at elevated temperatures. To be able to crystallize, the polymer chains must meet certain criteria: they should exhibit flexibility, regularity, and symmetry. Since most of the commercial polymers are derived from petroleum, transitioning to more sustainable materials requires the use of bio-based monomers. The goal is to develop new sustainable semicrystalline polymers by employing innovative design and synthesis strategies.

Despite significant progress, several open questions remain in understanding polymer crystallization. Factors such as nucleation kinetics, chain entanglement, molecular weight distribution, and processing conditions continue to influence the development of semicrystalline morphology in complex ways. Furthermore, the development of advanced polymer systems including novel architectures, copolymers and nanocomposites, introduces new variables that affect the crystalline properties. Given the strong impact of crystalline structure on the performance of polymers such as mechanical properties, barrier character or biodegradability, deepening our understanding of these factors is essential. Such knowledge is critical for the precise design and control of next-generation semicrystalline polymer materials.
