In this study, the effect of chitin nanofiber (ChNF) on the physical behaviors of cellulose nanocrystal (CNC) in suspension and solid states was investigated using polarized optical microscopy, rotational rheometry, and wide-angle X-ray scattering system. ChNF showed a significant effect on the cholesteric phase of CNC suspension, mainly owing to the electrostatic attraction and hydrogen bonding between ChNF and CNC. In turn, the increase of ChNF content reduced the size of the cholesteric domain. The applied shear force on the suspension changed the cholesteric phase to a nematic structure that was maintained after the solidification. This improved the mechanical strength of the resulted film along the shear direction.
