CCellulose is the most abundant polymer on Earth. As all polysaccharides, it offers an interesting alternative to oil-based polymers owing to its good carbon print performance and its biodegradability.
The research objectives are the understanding of dissolution and swelling mechanisms of cellulose coming from different sources and treated in various ways, the studies of solution thermodynamics and rheology of solutions and cellulose regeneration and processing and the preparation of new materials.

The research objectives are the understanding, control and prediction of the formation of different morphologies and structures that appear under flow of incompatible bio-based polymer blends in order to vary and improve the properties of final products.
All studied blends include one or several bio-based components (starch, PLA, PHA, cellulose derivatives).

The studied filled systems are very diverse, like suspensions of nano-fillers, of agglomerates, of starch granules and of synthetic micro-gels as well as composites reinforced by plant fibers in various matrices (thermoplastic polymers or lignin).
The research objectives are to understand the behavior of these fillers under flow, the elementary mechanisms for their dispersion, structuration and de-structuration of fillers under flow and to relate this information to the rheological behavior of the filled materials to their processing and final properties.
