A Direct Preparation of Cellulose Nanocrystals by ZnCl₂-Based Deep Eutectic Solvent

Polysaccharides
Here, we demonstrated a direct method to produce cellulose nanocrystals (CNCs) with a rod-like shape from microcrystalline cellulose by a ZnCl2-based deep eutectic solvent (DES) with a high yield (~80.1%).
