Summary

The authors group focused on adsorption of non-ionic surfactant molecules to an interface and examined active control of supercooling degree. Then it was clarified that it can be actively controlled supercooling by variation of surfactant concentrations. In this paper, in order to improve the controllability of the degree of supercooling, the authors mixed an amphoteric surfactant with pure water fixed at pH 4(The amphoteric surfactant molecules used in this experiment were cationic at pH 4.), and measured the degree of supercooling at various concentrations under voltage application. The characteristics of the supercooling degree in the case of amphoteric surfactant were clarified by comparing the results of voltage application and non-application.
