Rheological behavior of carboxymethylcellulose and cellulose

WebThe Cox-Merz empirical relationship between the linear (oscillatory) and nonlinear (steady-state) viscosities has been shown to be valid for many polymeric systems. Here, we present an equivalent expression to relate the linear ( G ′) and nonlinear ( N 1) elastic properties of viscoelastic systems. WebThe Cox-Merz rule establishes a connection between the complex viscosity η*(ω)measured in an oscillatory frequency sweep (at a fixed strain amplitude within the linear viscoelastic regime) and the steady shear viscosity η(γ )=σγ measured as a function of shear rate γ .
