Functional Materials based on Nanocelluloses and Polysaccharides

This research topic involves Gilles Sèbe and Frédérique Ham-Pichavant.

In the current context of sustainability, there is a growing interest in developing novel functional materials based on sustainable bioresources. In particular, nanocelluloses are increasingly considered as suitable building blocks for the elaboration of hierarchical materials, thanks to their nanosize dimensions and unique rod-like or fibrillar structure.

Because of their high specific strength, modulus and aspect ratio, nanocelluloses can significantly improve the mechanical performances of polymers, at low loading levels. They can also serve as stabilizing agents in Pickering emulsions, as matrix for the preparation of aerogels or foams, or as templating agent.

But to realize the full potential of these applications, the nanocellulose surface must be tuned by appropriate functions to control their dispersive, interfacial and self-assembling properties.

In this context, this research aims at developing novel nanocelluloses-based functional materials, through chemical tailoring of the nanocellulose surface. We’re particularly interested in developing systems where nanocelluloses are used as reinforcing agents, emulsifiers, biotemplates or responsive nanodevices.
