Abstract

Hydration behavior of polymers in aqueous solution is quantitatively detectable using dielectric spectroscopy in a high frequency range up to 50 GHz. Water molecules possess a relatively large dipole moment and form condensed hydrogen bond networks with a finite lifetime in the liquid state. The magnitude of the fastest relaxation mode observed in aqueous polymer solution with the same relaxation time as that of pure water reflects the amount of free water molecules. Then, one can evaluate hydration numbers of polymers. The second relaxation mode with a longer relaxation time corresponds to the exchange process of hydrated water molecules by free water.
