Outline of Final Research Achievements |
It is well known that the enriched catechol residues are found in mussel’s byssus showing a high adherent ability in water. We hence tried to replace the hexadecylpyridinium moieties of a stoichiometric poly-gamma-glutamate ion-complex (PGAIC) with dopamine molecules and succeeded in developing dopamine:PGA supragels at room temperature without risky chemicals/expensive catalysts. This new material was tentatively called dopamyl PGA (dmPGA). The rheological research implied that dmPGA possesses potential as self-healing gels. Furthermore, the metal adsorption tests indicated that the capabilities (particularly for divalent cations) of dmPGA, along with a hyperbolic curve, are much superior to PGA and polyacrylate, suggesting its potential application for the effective (simultaneous) removal of various toxic metals.
