| Outline of Final Research Achievements |
We succeed in synthesizing a hybrid thin film/membrane featured with a superlattice structure by combining hydroxide nanosheet and graphene oxide at the molecular level. It showed a highly selective ion separation/transport property with the relative selectivity of monovalent to trivalent cations reached above 30. In addition, we discovered that hydroxide nanosheets exhibited a very high ionic conductivity approaching 10-1 S/cm. This conductivity is 10 to 100 times higher than that of conventional hydroxide ion conductor. In contrast, the conductivity in the thickness direction of the nanosheets was found to be on the order of 10-6 S/cm. Such a highly anisotropic conduction characteristic is thought to be derived from the two-dimensional structure of nanosheets.
