Outline of Final Research Achievements

We have investigated in this study to develop methodologies for constructing new soft materials, utilizing the very strong non-covalent interaction called “charge-assisted hydrogen bonding”. In particular, we have concentrated on supramolecular polymer gels based on synthetic polymers, thus finding that supramolecular polymer gels can be obtained simply by mixing solutions of polymers with amidine groups and those with carboxy groups, followed by evaporation. We have found the viscoelasticity of these gels changes reversibly in response to the changes in temperature, and also that in most cases they do not show fluidity at low temperature, exhibiting a rubber-like plateau region with storage modulus of larger than 1 MPa.
