Research Abstract

Polymer gels show a dramatic change in volume in response to change in solvent composition, pH, ionic strength and temperature. They contract upon appliction of an electric field. Further, water-swollen polymer gels can convert chemical energy into mechanical energy. These properties lead to the vitality of polymer research and development of a diversity of interests in polymer gel systems. To elucidate the stimulus-response mechanism for such polymers is one of important problems for gel science and for development of new polymer materials and polymer gel design. The properties of polymer gels are closely related to their structures and dynamics. From such situations, the establishment of methods for elucidating the structures and dynamics of gels under external force is important for making reliable polymer gel design and developing new advanced polymer gels. From such a background, we have successfully developed by three-dimensional NMR imaging system and high field gradient NMR system capable of obtaining three-dimensional stimulus-response image patterns about spin density and diffusion coefficient distribution diffusion coefficients in the wide range of 10^4-10^<11> cm^2/s, and to elucidate the stimulus-response mechanism of polymers gels.
