Synthesis, Characterization, Structure and Properties of Novel Non-Isocyanate Polyurethanes

To prepare novel biocomposites between cellulose (nano)fillers (nanofibers and nanocrystals) and NIPU thanks to their propensity to set up hydrogen bonding and interfacial covalent cross-linking with them.ESR9: To design biocomposites from novel waterborne or solvent-free functional NIPU polymers, where interface aspects and dispersion considerations are emphasized in order to achieve desired properties and processing characteristics.

Polysaccharide Monooxygenases (LPMOs) for Advanced Nanocellulose Materials

LPMOs (lytic polysaccharide monooxygenases) are oxidative enzymes that enhance cellulose fibrillation by introducing charged carboxyl groups onto the cellulose surfaces in aqueous reaction conditions. The use of LPMOs in production of nanocelluloses could reduce the need of hazardous chemicals and facilitate more environmentally friendly processes. The aim of this subproject is to produce recombinant LPMOs …

Bio-based binders for molded cellulose fibers

Natural binders are inexpensive, biodegradable, environmentally friendly and renewable, but usually form weaker bonds and slightly harder to apply. The objective of the project is to develop and optimize the process of using various plant polysaccharides as binder for holocellulose fibers and cellulose nanofibrils (CNF). The selected polysaccharides are further functionalized to improve interfacial adhesion …
