| Outline of Final Research Achievements |
We have successfully fabricated a water-dispersion solution of Prussian-blue (PB) nanoparticles(NPs) and their mono-particle film on a self-assembly monolayer film via chemical adsorption between interdigitated Au electrodes. The mono-particle film was heated at 120°C to chemically connect the PB NPs into each other. Based on the Bode-plot analyses, the non-heated film showed low proton conductivities in a low-frequency region, while high proton conductivities appeared in a high-frequency region from the low-temperature heated film. The high proton conduction (10-1 Scm-1) of the heated film is superior performance along with a water-retention ability (humidity dependence) in comparison with Nafion films. The proton conduction is derived from the vehicle mechanism in the non-heated films. The proton conduction is transferred into Grotthuss mechanism in the heated films. These results are the first report on a new function as a pseudo single crystalline films composed of NPs.
