| Outline of Final Research Achievements |
We synthesized biomass hybrid materials in a molecular level. Cellulose triacetate-b-poly(g-benzyl-L-glutamate) was synthesized, and, for the first time, exhibited microphase separation as cellulosic materials. Diblock methylcellulose derivatives having ionic oligo(amino acid)s and oligomers of hemicelluloses were also synthesized. As a result, we found sufficient conditions for methylcellulose-based supramolecular hydrogels: a sequence of, at least, 10 tri-O-methyl-glucosyl residues for hydrophobic blocks, and functional groups for hydrogen bonds for hydrophilic blocks. Moreover, thermoresponsive supramolecular hydrogels comprising end-functionalized methylcelluloses showed properties of slow drug release.
