title = "DURABILITY OF CELLULOSE NANOMATERIALS UNDER INDUSTRY RELEVANT SHEAR STRESSES",
abstract = "The effects of high-shear flow on cellulose nanocrystals (CNCs) were studied to characterize potential impacts of industrial processing on these materials. A microcapillary rheometer was employed to study the rheological characteristics of aqueous CNC suspensions at concentrations ranging from 1.5 wt\% to 12.1 wt\%. Increased cellulose content in the suspensions produced increased viscosities. A Sisko model was successfully fit to the data which display high shear Newtonian plateaus. Shear rate sweeps at these concentrations failed to fully reduce to a master curve. Furthermore, repeated testing of the same sample volume at nearly 800000 s-1 led to a permanent decrease in viscosity for all samples. Atomic Force Microscopy (AFM) probed CNC morphology to observe any changes in the CNC dimensions which may have contributed to this phenomenon. AFM results indicate significant decreases in both height and length of the CNCs after repeated testing at high shear rates.",
