Extensional rheology of cellulose-ionic liquid solutions
Various cellulose-ionic liquid solutions were measured with a rotational plate-andplate rheometer and a Capillary Break-up Extensional Rheometer (CaBER). Comparison of the shear and extensional rheological properties showed good agreement in some cases. The CaBER, however, seems to be more sensitive to small variations in solute composition. INTRODUCTION Since almost a decade now, nonderivatizi...
متن کاملShear and extensional rheology of cellulose/ionic liquid solutions.
In this study, we characterize the shear and extensional rheology of dilute to semidilute solutions of cellulose in the ionic liquid 1-ethyl-3-methylimidazolium acetate (EMIAc). In steady shear flow, the semidilute solutions exhibit shear thinning, and the high-frequency complex modulus measured in small amplitude oscillatory shear flow exhibits the characteristic scaling expected for solutions...
متن کاملRheology of liquid crystalline polymers
Concepts which may be used in interpreting the complex rheology of liquid crystalline polymers are reviewed. Some of them are taken from the nematodynamics of low molecular weight liquid crystals as described by the Leslie—Ericksen theory, others are intrinsic to the viscoelasticity of ordinary polymers. Tentatively, these concepts are used to construct an explanation of the band texture which ...
متن کاملLiquid Crystalline Behavior of Hydroxypropyl Cellulose Esterified with 4-alkoxybenzoic Acid
A series of 4alkyoxybenzoyloxypropyl cellulose (ABPC-n) samples was synthesized via the esterification of hydroxypropyl cellulose (HPC) with 4-alkoxybenzoic acid bearing different numbers of carbon atoms. The molecular structure of the ABPC-n was confirmed by Fourier transform infrared (FT-IR) spectroscopy and H NMR spectroscopy. The liquid crystalline (LC) phases and transitions behaviors were...
متن کاملLiquid-Liquid Equilibrium for the Ternary Systems of Solvent+ m/o/p-Cresol+Water: Thermodynamic Modeling
In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...
