Amorphous Tantalum Oxide Proton Conductor Derived from Peroxo-Polyacid and Its Application for EC Device
Two kinds of solid state ECD prototypes were fabricated by combining electrochromic films and a Ta2O5.nH2O proton conducting film. Electrochromic characteristics of these devices were comparable to those using liquid electrolyte. We also demonstrated reversible EC characteristics of Prussian blue with insertion and extraction of proton, using a Ta2O5.nH2O film.
