Topic description
Ce projet vise à valoriser la lignine, l'un des principaux composants des biomasses lignocellulosiques, en lui conférant de nouvelles fonctionnalités grâce à une approche hybride combinant la mécanochimie et la biocatalyse. L'objectif est de fonctionnaliser ce biopolymère afin d'améliorer sa solubilité, sa thermoplasticité et son affinité avec des matrices hydrophobes, facilitant ainsi son intégration dans matériaux biosourcés. Le projet repose sur une étude approfondie des propriétés structurelles, morphologiques, chimiques et thermiques des lignines, tant brutes que fonctionnalisées, afin d'élucider les mécanismes et l'efficacité de la modification enzymatique, assistée ou non par la bio-extrusion. Dans un second temps, la lignine modifiée sera incorporée dans des matrices polymères afin d'évaluer les performances techniques et le potentiel industriel des matériaux obtenus. En alliant durabilité et innovation méthodologique, ce projet propose une voie concrète pour le développement de matériaux biosourcées à partir de la lignine, présentant de potentielles propriétés antibactériennes et antioxydantes.

This project aims to valorize lignin, one of the main components of lignocellulosic biomass, by imparting new functionalities through a hybrid approach combining mechanochemistry and biocatalysis. The objective is to functionalize this biopolymer in order to improve its solubility, thermoplasticity, and affinity with hydrophobic matrices, thereby facilitating its incorporation into bio-based materials. The project relies on an in-depth investigation of the structural, morphological, chemical, and thermal properties of lignins, both non-modified and functionalized, to elucidate the mechanisms and efficiency of enzymatic modification, with or without bio-extrusion assistance. In a second stage, the modified lignin will be incorporated into polymer matrices to evaluate the technical performance and industrial potential of the resulting materials. By combining sustainability with methodological innovation, this project proposes a concrete pathway for the development of bio-based materials derived from lignin, exhibiting potential antibacterial and antioxidant properties.
