Abstract

In this study, we tried to find out the formation mechanism of hyper mobile water at various pH and NaCl concentrations to understand the effect of the electric field intensity around polymer chains. The hydration state of PAA chains were also examined. As a result, we found that 1 the hydration number (NH2O) and the number of hyper-mobile water (N-hyper) per monomer unit of PAA increased with the charge density of polymer chain. 2 the number of hyper-mobile water (Nhyper) decreased at high salt concentration (NaCl 0.1mol/l).
