Evolution of viscosity η versus shear rate ${\dot{\gamma }}_{\mathrm{w}}$ obtained by Couette geometry for chitosan CHI solutions and cellulose nanofiber-filled chitosan CNF/CHI suspensions of (a) 1.7% and (b) 3.3% (w/w) chitosan, containing different CNF contents (0.2–0.4% (w/w)) and obtained in hydroalcoholic conditions.
