Summary:

Investigations on the rheology and phase behavior of aqueous CNC dispersions have been used to develop processes for making CNC coatings with controlled properties. We report how the interplay between dispersion microstructure, shear, and drying conditions affect the morphology, optical properties, and mechanical properties of cellulose nanocrystal (CNC) coatings. These results provide a foundation for functional coatings for a range of optical and sensing applications.
