Using a tensiometer and the Welhelmi plate method, we carried out a series of measurements of surface tension for various concentrations and temperatures of colloidal solutions with three promising surfactants: CTAB, SLS, and Tween-80. These surfactants in dry form were mixed with water to make a 1% solution and then diluted to weaker concentrations of up to $$3\cdot 10^{-8}$$ mol/l.

The surface tension values were measured over the temperature range of 20 to 70°C. For several concentrations of the surfactant SLS, the first derivative of the surface tension with respect to the temperature was found to be positive (∂σ/∂T > 0), which means that the interface can be self-wetted. This property may be important in preventing formation of dry spots, which will improve heat transfer in heat pipes.",
