Nanostructured Prussian Blue–polypyrrole composite coatings with electrochromic properties
Résumé
The Prussian Blue-polypyrrole (PB/PPy) composite materials were obtained by a chemical redox process in a mixed solution of iron(III), hexacyanoferrate(III) and pyrrole with a nitrate supporting electrolyte. The morphology of the composites (as a sedimented powder or a film on the ITO-glass electrode surface) varied depending on the composition of synthetic solution.
