Rheological characteristics of CTAC aqueous solutions under the combined effects of shearing and temperature

The rheological properties of CTAC/NaSal aqueous solutions (NaSal had same molarity with CTAC.) with different concentrations were experimentally investigated at different temperatures ranging from 10°C to 70°C and different shear rates from 1 s^-1 to 300 s^-1. There were a critical shear rate and a critical temperature for all measured surfactant aqueous solutions with mass concentrations ranging from 0.001% to 0.015%. The effects of temperature and shearing on viscosity properties of surfactant solution varied with the concentration. Rheological characteristics of viscosity showed complex variations under the combined effects of temperatures and shearing even for the solutions with same concentration. Surfactant solution with relatively high concentration thickened for the second time when suffering from strong shearing and high temperature.
