Technical Abstract: The rheological properties of microfibrillated cellulose (MFC) produced from agricultural residue corn stover were investigated. The corn stover MFC gels exhibited concentration-dependent viscoelastic properties. Higher corn stover MFC concentrations resulted in stronger viscoelastic properties. The analysis for moduli of different concentrations and stress relaxation measurements indicated that the corn stover MFC gels were physical gels, meaning the cross-linkers between the molecules exhibited physical interactions. The non-linear steady shearing rheological properties studies implied that the corn stover MFC gels exhibited shear thinning behavior, which can be correlated with the Power-Law Constitutive Equation. The function and behavior of the corn stover MFC gels suggest that this kind of starch-based biomaterial could be a potential candidate for applications in cosmetic gels and skin wound care materials.
