Correlations between rheological behavior and intrinsic properties of nanofibrillated cellulose from wood and soybean hulls with varying lignin content

Effects of raw material and chemical composition were considered relative to the intrinsic properties rheological behavior nanofibrillated cellulose aqueous suspensions (CNFs). Atomic force microscopy, Fourier-transform infrared spectroscopy, surface chemistry analysis, thermal gravimetrical zeta-potential used study morphology, composition, charge density, as well colloidal stability different CNFs. Regarding samples, steady-state oscillation studies CNF obtained from wood soybean hulls performed. An interesting correlation was found between their properties. Soybean presented lower viscosities than which could be related morphology density. Additionally, unbleached (sb-LCNF) showed yield stress compared with other attributed presence pectin. Furthermore, compositions samples affected properties, on crystallinity.
