Appel à candidatures, Stage
Sujet du stage : study of the effectiveness of sulfonation in the production of microfibrillated cellulose containing lignin (LCMF) by ultrafine wet grinding.
Le LGP2 propose un stage de 6 mois, niveau M2
Currently, research is oriented toward the use of microfibrillated cellulose (MFC) as a replacement for fossil-fuel based materials, e.g., in composites, coatings and packaging materials.
The typical raw material is a chemically delignified, bleached cellulose pulp, although more and more research is oriented towards the study of the potential use of unbleached pulp. Indeed, several efforts have been made to find cost-effective methods and raw materials to produce MFC in a more environmentally friendly way. Actually, the extraction of cellulose nanofibrils containing lignin (LCMF) makes possible the use of a cheaper raw material while eliminating the bleaching stage. In fact, the effect of the presence of lignin is still debated in the scientific literature...
