✦ Synopsis

Results found on stab&y of Prussian Blue (PB) films deposIted on IT0 electrodes show that these films can withstand more than 10' cycles around the reduction system [Prussian Blue-Prussian Whte (PW)] The greater quantity of water molecules mside the water-stored films avoid its soluhhzation durmg the oxidation process, although stahhty 1s slightly decreased when cycled around the reduction system (PB CI PW) only K+ inserted mto the film suffers a recorgamzahon process durmg cycling around the whole voltammogram and allows the total oxidation to Prussian Yellow (PY) and the successive cycling around the oxidation system (PB u PY) The presence of Fe&N):-in the me&urn can avoid the soluhllzatlon process durmg the oxldatlon of PB to PY However, the film loses Its adherence
