This University of Grenoble doctoral thesis was prepared in the LGP2 laboratory under the supervision of Ana Maria Botelho do Rego, Associate Professor, Instituto Superior Técnico (Portugal), of Frédéric Pignon, CNRS Research Director, Laboratoire Rhéologie et Procédés, Grenoble and of Naceur Belgacem, Professor, Grenoble INP-Pagora / LGP2.

One of the main challenges in the context of biocomposites development is to replace petroleum-based materials with bio-based. Because of their natural origin, relatively high strength and the ability to form transparent products, cellulose nanofibers have a large potential for application in the composite materials.

This work was focused on the optimization of cellulose nanofiber production methods using biochemical and mechanical treatments. Then, the rheological and structural properties of these nano-elements in aqueous media were investigated. Finally, the production of latex-based composites was carried out. The questions of homogeneous dispersion of cellulose nanofibers in the matrix and the interactions between these two components were particularly addressed.
