摘要：In this work, short rod-like cationic cellulose nanocrystals (AH-CNCs) were prepared by sodium periodate oxidation combined with deep eutectic solvent method. The effects of different content AH-CNCs on the properties of the emulsion were studied. With the increase of AH-CNCs content, the diameter of emulsion droplets decreased and the stabilization time prolonged. The electrostatic attraction between the negative charge accumulated at the oil-water interface and AH-CNCs with positive charge improved the stability of the emulsion. Then, the rheological properties showed the interaction of nanocellulose in the continuous phase increased the viscosity of the emulsion. In addition, the droplet diameter of emulsion of 120 s was smaller at different ultrasonic time, the particle size distribution of emulsion changed from monodisperse to polydisperse with the increase of oil volume, the salt concentration had little effect on the droplet size of emulsion, and the preparation of emulsion under acidic conditions was more stable.
