(54e) High Shear Behavior of Nanocellulosics

Nanocellulosics, which are typically found in the form of Cellulose nanocrystals (CNCs) and Cellulose Nanofibrils (CNFs) provide promise as both filler and reinforcement materials. While much research is currently investigating potential applications of nanocellulosics, little is understood about the impact of high rate and stress, associated with many conventional processing techniques, on the rheology and structure of these materials. Our research investigates high shear rheology of nanocellulosics, highlighting impacts of temperature, concentration, and stress on the flow behavior and physical properties of these materials. We have characterized the potential degradation and relaxation characteristics of these materials. Furthermore, we have demonstrated the ability to generate master curves based on time-temperature and time-concentration superposition principles.
