Cellulose and its derivatives can be at the origin of liquid crystalline (LC) networks. Films produced from LC solutions can be manipulated by the action of moisture allowing, for instance the development of a soft motor driven by humidity. Cellulose Nano Crystals (CNC), which combine cellulose properties with the specific characteristics of nanoscale materials, can also be at the origin of liquid-crystalline chiral nematic phases. Considering the liquid crystalline features that both, cellulose derivatives and CNC, can acquire the effect of the CNC into the cellulose-based matrix is addressed and investigated by coupling Rheology with NMR spectroscopy - Rheo-NMR.
