Abstract
Poly(3,4-ethylenedioxythiophene) (pEDOT) films have been modified by iron, cobalt and nickel hexacyanoferrate analogues (Mehcf). Synthesis of these materials was performed using multicyclic polarisation of pEDOT/Fe(CN)63−/4− films in aqueous electrolytes containing nickel, cobalt and iron salts. Resulting materials are electroactive and show good reproducibility during hundreds of polarisation cycles. Specific capacitance of hybrid materials is equal to 70, 70 and 50 F cm−3 for pEDOT/Cohcf, pEDOT/Nihcf and pEDOT/Fehcf, respectively. Scanning electron microscopy shows that obtained films are homogenous and compact on the micrometer scale.
