Effect of salt addition on the viscosity of the NOHM-based fluids. (a) Viscosities of NOHM-I-HPE solutions as a function of temperature. Dashed lines represent NOHM-I-HPE solutions with 0.1 M NaCl addition. (b) Percentage decrease in viscosity of NOHM-I-HPE solutions of 10, 20, 30, 40, and 50 wt % NOHM loading with the addition of 0.1 M NaCl at 20 °C.
