Cellulose nanoparticles, in addition to their low weight, have advantages such as renewability, recyclability, processability, and biocompatibility. Films containing cellulosic nanoparticles are used as a coating and intermediate layer in the packaging products due to their good performance and resistance to oxygen penetration. Because of the natural origin of cellulose nanoparticles, they are obviously can reduce environmental pollution loading, when being replaced with some artificial reinforcements. The properties of cellulosic nanoparticles can be accomplished by investigating the rheology of nanoparticles gel. Cellulose nanoparticles suspensions are widely used as coatings, in composites, 3-D printing, and cellulosic membrane. For the aforementioned applications, cellulose nanoparticles suspensions are exposed to shear forces. Thus, precise knowledge of the rheological behavior of cellulose nanoparticles suspensions is necessary under the shear force associated with such industrial processes. Many studies have been done on the rheological properties of cellulose nanoparticles that provide information on the properties of these materials and their behavior when used. The present review paper is discussed the rheological properties of cellulose nanoparticles and concepts such as linear viscoelastic, storage/ loss modulus dependency on frequency, shear flow behavior index such as viscosity and shear stress as a function of shear rate.
