Abstract

Quartz crystal microbalance (QCM) measurements of soft/wet materials during the freezing-thawing process were carried out by admittance analysis of the QCM oscillations using water as the soft/wet sample. The influence of the freezing and thawing of water on the QCM response was examined as a function of temperature based on the resonant frequency, fs, resonant resistance, R, and the equivalent circuit parameters of the QCM system determined by admittance analysis. The supercooled freezing and thawing behaviors of water were monitored from a viscoelastic point of view using the QCM. The QCM response and the liquid–solid phase changes in water were evaluated based on the LCR model through admittance analysis.
