Biobased nanoparticles at the interfaces for powdered fluids – DryWater

Pickering emulsions (which means interface stabilized by particles) have specific properties of very high stability. Under certain conditions drying such emulsions may result in systems in the form of "dry oil" or "dry water" powders depending on the nature of the emulsion (direct or inverse). The DryWater project aims at probing hydrophobic functionalization of biobased particles (cellulose nanocrystals) that can stabilize direct, reverse and multiple Pickering emulsions. A new method of functionalization respectful of the environment with hydrophobic molecules issued from the vegetable world is proposed. In this project, the conditions for obtaining these new direct and inverse emulsions will be developed in order to obtain the powders.
