Dielectric properties of supercooled glycerol-water solutions

Abstract

Little concentrations of a hydrogen-bonding impurity as glycerol, tend to break the hydrogen bonded structure of pure water and to prevent crystallization. The properties obtained by extrapolation are certainly those of pure water: Tg is in good agreement with the glass transition temperature of vitreous ice; εs(T) shows the variations predicted by the model of RICE. Our results support the idea of a continuity of states between supercooled and amorphous solid water.
