Integrated, highly crystalline and water stable coordination framework films on various substrates and water-assisted protonic conductivity

Abstract

The integrated, highly crystalline and water stable Prussian blue analogue films were successfully fabricated on the porous α-Al₂O₃, the conducting ITO and the flexible non-woven fabric substrates, respectively, using the self-assembly approach. The proton conduction was investigated for both powdered pellets and the film on the porous α-Al₂O₃ substrate. This study promotes the practical applications of MOF-based proton conductors in various devices.
