Text of Abstract
There is significant interest in producing macroscale materials with anisotropic optical, mechanical, or electrical properties via the controlled fluid phase assembly of rod-like nanomaterials. However, there is still relatively limited understanding of these systems’ phase behavior, rheological properties and microstructural relaxation after shear cessation. In this study, rheology and rheo-optics were used to understand the behavior of the aqueous lyotropic system, sulfonated cellulose nanocrystals (CNC). Understanding post-shear relaxation is critical to understanding properties of silidified materials.
