The colloidal suspensions of aqueous cellulose nanocrystals (CNCs) are known to form liquid crystalline (LC) systems above certain critical concentrations. From an isotropic phase, tactoid formation, growth, and sedimentation have been determined as the genesis of a high‐density cholesteric phase, which, after drying, originates solid iridescent films. Herein, the coexistence of a liquid crystal upper...
Cellulose Nanocrystals
Rod‐like cellulose nanocrystal aqueous colloidal suspensions can be prepared from eucalyptus kraft pulp. In article number 2108227, Maria Helena Godinho and co‐workers show the formation of a liquid crystalline (LC) phase atop an isotropic phase, inverted from the typical high‐density LC phase. The bounciness of the particles is attributed to the presence of air. The behavior...
