Enthalpy changes generated by titrating 3.2 mM Pluronic P123 in water at varied temperatures (shown in the legend) in the range 20 to 40 °C. The titrant concentration is well above the critical micelle concentration (CMC) (0.313 mM at 20 °C [13]). The enthalpy change for each injection was obtained by ITC and then was standardized by dividing by the amount of the injected Pluronic for each injection. The maximum of the first derivative of the enthalpogram (solid lines) indicates the CMC.
