  • Influences of Surfactant Concentration on Supercooling Degree of Cationic Surfactant-pure water Mixture

抄録

<p>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 degree by variation of surfactant concentrations. In this paper, an amphoteric surfactant that exhibit cationic property was used by fixing the pH of the surfactant-pure water mixture (surfactant mixture) for the purpose of further improving the controllability of the supercooling degree. And then The supercooling degree of the surfactant mixture was measured by varying of surfactant concentration. And the characteristics of the supercooling degree when an amphoteric surfactant that exhibit cationic property was used were clarified by comparing with the results when a non-ionic surfactant was used.</p>
