Schematic image of cellulose hydrogel formation. Cellulose molecules are depicted as cross-section and water molecules are not depicted here.
On the basis of these analyses, a schematic image of cellulose regeneration in the present system can be drawn as in Fig. 2. Namely, the cellulose molecules stack with hydrophobic interactionto form monomolecular sheets, which thenlineupbyhydrogen bonding.
