n addition to light weight, cellulose nanoparticles have advantages such as renewability,
recyclability, processability, and biocompatibility. Films containing cellulose
nanoparticles are used as coatings and intermediate layers in packaging products due to
their good performance and oxygen barrier. Given its natural origin, it is obvious that
the replacement of some synthetic reinforcements with these nanoparticles can reduce
environmental pollution. The properties of cellulose nanoparticles can be determined by
investigating the rheological properties of the nanoparticles gel. Suspensions containing
cellulose nanoparticles are widely used in the pulp and paper industries as coatings, in
composites, 3D printing, and as cellulose membranes. For these applications, suspensions of
cellulose nanoparticles are exposed to shear forces. Therefore, having accurate knowledge
of the rheological behavior of suspended cellulose nanoparticles under high shear force
in relation to such industrial processes is essential. There have been many studies on
the rheological properties of cellulose nanoparticles that provide information about the
properties of these materials and their behavior during usage. In the present review, the
rheological properties of cellulose nanoparticles and concepts such as linear viscoelastic,
properties such as frequency dependent storage modulus/loss modulus, shear fow behavior
indices such as apparent viscosity and shear stress as a function of shear rate are discussed.
