About the Insoluble to the Soluble Prussian Blue Transformation

Interfacial and nano-gravimetric results are analyzed together with spectro-electrochemical in situ results in order to study the electrochemical transformation of the Prussian Blue films from the freshly deposited to the stable form. This is a complex process that implies apparently the lost of water molecules and the entrance of potassium ions into the ferrocyanide vacancies of the crystalline structure.
