The position combines chemical characterization, structure–composition analysis, material formulation and processing , with the ultimate objective of establishing innovative and sustainable valorization pathways for complex biorefinery side-streams. Research objectives The researcher will investigate selected side-products generated from biorefinery processes and establish relationships between their chemical composition, molecular structure, physicochemical properties and potential applications in polymeric materials . The research will involve: Comprehensive chemical and physicochemical characterization of biorefinery side-products. Identification and quantification of the main chemical constituents and functional groups. Separation, purification and/or fractionation of selected components where appropriate. Identification of reactive or functional molecules suitable for incorporation into polymeric systems. Development of strategies for the chemical or physical modification of side-products. Evaluation of their potential as polymer building blocks, reactive components, crosslinkers, fillers, modifiers or functional additives. Development of bio-based thermosetting resins and polymeric materials . Development of bio-based or partially bio-based coatings . Development of polymer composites and multifunctional composite materials incorporating valorized biorefinery side-products. Optimization of formulations and processing conditions. Characterization of the resulting materials in terms of chemical, thermal, mechanical, rheological and functional properties. Establishment of structure–processing–property relationships. Research methodology The project will combine analytical chemistry and materials science approaches.
