Effective rheology mapping for characterizing polymer solutions utilizing ultrasonic spinning rheometry

We propose a practical map representation termed rheology mapping for comprehensively evaluating the dependence of viscoelasticity on applied shear deformation and timescale represented by oscillation frequency, utilizing ultrasonic spinning rheometry, which has excellent applicability to wide variety polymer solutions. The was two typical kinds One is carboxymethyl cellulose (CMC) aqueous solution, well-known viscous thinning fluid. other polyacrylamide (PAM) solution generally considered as viscoelastic fluid while its difficult be evaluated standard torque-type rheometer. solutions showed notable rheological properties. both CMC PAM vary widely from elastic viscous, depending rate, strain, frequency. also revealed clear viscosity solutions: rate strain. These results provide quantitative support findings in reports associating these macroscopic properties with microscopic dynamics coils.
