5.3.1 MorphologyMorphology of nanocelluloses is one of the most important parameters to control during production and it depends on the cellulose source and the production method (Table 5.7). Indeed, depending on the source of the cellulose, the initial fibers have different lengths, MFC angles, and amounts of residual lignin and hemicelluloses, or other characteristics when they come from wastes that also influence the final CNF and CNC morphology.
