Advanced Synthesis and Structural Design of High Performance Biodegradable Polymers Utilizing Furandicarboxylic Acid and Citric Acid

While the transition toward biodegradable polymers and materials derived from biomass is driven by strict environmental regulations, overcoming the performance disparity with conventional petroleum plastics remains a persistent challenge. However, the paradigm of polymer science is shifting from merely matching these traditional materials to actively surpassing their physical capabilities through advanced structural design. In this presentation, we demonstrate that strategically engineered biodegradable polymers can deliver unprecedented composite physical properties. By utilizing monomers derived entirely from biomass, specifically furandicarboxylic acid for exceptional structural rigidity alongside citric acid to introduce multifunctionality and complex networking, we architected a novel series of advanced polymers. Crucial to this breakthrough were significant improvements in synthesis methodologies coupled with innovative catalyst design and precise compositional tuning. Furthermore, we comprehensively evaluated the macromolecular architecture through advanced structural analysis techniques, including the precise determination of sequence distribution and two-dimensional correlation spectroscopy. These deep structural insights allowed us to meticulously tailor the polymer network, resulting in materials that exhibit superior mechanical strength and multifaceted functionalities without compromising their inherent biodegradability. Ultimately, this work highlights that the next generation of biodegradable polymers can redefine the limits of materials science, moving beyond simple environmental replacements to offer true performance superiority.
