418 Study on active control of supercooling degree by addition of surfactant : Investigation on effect of adding smaller other surfactant molecules

Abstract

Authors examined active control of supercooling degree by using adsorption of surfactant molecules to an interface, and it was clarified that it was possible to actively control supercooling degree by variation of surfactant concentrations. In this paper, when other surfactant molecules with smaller sizes are added to let them be adsorbed to the interface without adsorption of original surfactant molecules at a critical micelle concentration where adsorbed area of original surfactant molecules to the interface becomes a maximum, effect of the addition of smaller surfactant molecules on the supercooling degree is investigated.
