Despite the typically low content of sulfate half-esters, the existence of the charged group makes the suspensions colloidally stable due to electrostatic repulsion. (8) This means that at pH values higher than that, the CNCs carry a net negative charge. The sulfate half-ester groups have a negative logarithm of acid dissociation constant (p K a) that is approximately 2. Sulfuric acid is a common reagent, and in addition to the hydrolysis at the dislocations, it simultaneously esterifies the cellulose nanocrystal surface, which leads to sulfate functionalities in addition to the hydroxyl groups on the surface. The interparticle attraction of CNCs can be reduced by introducing like-charged groups onto the particle surfaces. This Review provides an overview of achievements in the coupled analytics, as well as our current opinion about opportunities to unravel the structural distinctiveness of cellulose nanomaterials. While optical techniques, scattering, and spectroscopy are often used to complement rheological observations, coupling them in situ to allow simultaneous observation is paramount to fully understand the details of CNC assembly from liquid to solid. Rheometry is combined with other characterization methods to allow direct analysis of the structure development in the individual hierarchical levels. Rheological characterization is essential for investigating flow properties however, bulk material properties make it difficult to capture the various length-scales during assembly of the suspensions, for example, in simple shear flow. Although these assemblies have the potential for future renewable materials, details about structures on different hierarchical levels that span from the nano- to the macroscale are still not unraveled. The resulting hierarchies are optically active materials that exhibit iridescence, reflectance, and light transmission. The orders range from nano- to macroscale with the contributions of individual crystals, their micron clusters, and macroscopic assemblies.
