摘要: Rheological behavior of the concentrated cellulose/1-butyl-3-methylimidazolium chloride ([BMIM]Cl) solutions was investigated. As polymeric fluid, cellulose in [BMIM]Cl display a marked elastic under shear flow. The dependence viscosity η, and dynamic modulus, on concentration, average degree polymerization (DP) temperature is discussed. At lower concentrations degrees (DP), show viscous, inelastic at low frequencies rate. higher concentration DP, are more Such also have some usual rheological properties. responses revealed that Cox–Merz rule did not hold for these high deformation Plotting storage modulus G′ against loss G″ gave almost master curve which independent with slope about 1.651 10 wt% solutions. This value indicates existence microheterogeneity solution system.
