Descriptif des activités de recherche

The method we use consists first of creating functionalized polysaccharides using simple chemical reactions and/or amphiphiles by grafting bio-sourced lipids. As indicated previously, the grafting of frustoconically shaped cyclodextrins could have a unique impact on the structure of the polysaccharides. Due to their abundance of plant resources, their bacterial origin, and their low cost, we have chosen Poly galactomannan, dextran and cellulose as starting polysaccharides. However, to obtain a precise structure/property study, it is essential to characterize in depth the modified polysaccharides due to their different characteristics. A crucial step is the realization of the mass spectrometry of the modified polysaccharides, and we count on the help of the mass spectrometry team of LAMBE for the sequencing and the characterization of the modified polysaccharides. We will then evaluate these modified polysaccharides as binders with silicon in the lithium-ion half-cells at the LRCS. For the electrochemical storage of energy, this innovative method will allow us to develop various types of binders from abundant and renewable polysaccharides.
