Research Abstract

Water-swollen crosslinked polymer gels deform by the application of an electic field. For this, application of polymer gels to electrically-activated devices have been widely wtudied using these deformation properties. From such situation, in order to clarify changes in macroscopic structure and dynamics of water molecules in crosslinked poly (methacrylic acid) gel by the application of electric field through the observation of microscopic information at the molecular level, ^1H NMR imaging patterns with with information about the spatial distribution of ^1H spin density and ^1H spin-spin relaxation time T2 of water molecules in the polymer gel have been successfully measured. From these experimental results, we have elucidated the mechanism of shrinkage process of polymer gel and migration of paramagnetic metal ion in polymer gel under electric field. Futher, the application of these research works to molecular design of polymer gels has been usefully studied.
