原始语种摘要: Abstract(#br)The effect of sonication on a highly concentrated commercial suspension of cellulose nanocrystals (CNCs) and the resulting rheological properties have been investigated. Rheology and structural analysis techniques (atomic force microscopy, small-angle X-ray scattering, transmission electron microscopy and dynamic light scattering) were used to characterize the CNC suspension before and after sonication as a function of concentration. The highly concentrated CNC suspension, which does not contain aggregates, as shown by AFM and TEM imaging, turns from a “gel” form into a “liquid” form after a sonication treatment. The self-organization properties of as-prepared and sonicated suspensions were compared by the determination of their phase diagrams and flow rheology was performed...
