Text of Abstract
Aqueous cholesteric dispersions of cellulose nanocrystals can form planar domains that give rise to selective reflection of light. However, achieving solid films domains with consistent saturation colors requires controlling the helix packing and alignment during drying. This work showed how the combination of concentration, orbital shear, and speed of drying could be used to achieve large domains with controlled morphology and optical properties.
