G0600501 Investigation on effect of surfactant on ice adhesion force

Abstract

Ice adhesion force to a cooling solid surface caused many troubles accompanied by larger economical loss. Thus, the methods to reduce ice adhesion force to the solid surface were studied from various viewpoints. However, most of those methods were based on surface modification of the solid. In this paper, paying attention to adsorption of hydrophobic group of surfactant molecular to a copper surface, pure water with much smaller surfactant was frozen on the copper surface at -5℃, after which it was clarified that addition of the surfactant caused decrease in the ice adhesion force from comparison with ice adhesion force without the surfactant.
