Electrochemical Behavior of Hybrid Films Composed of Copper Hexacyanoferrate and Conducting Polymer

Sa？etak Hybrid organic / inorganic films, composed of poly 4-aminoquinolidine (PAQ) matrix and Prussian blue – like copper hexacyanoferrate (CuHCFe) redox centers were prepared. Platinum disk (Pt) was used as a conductive substrate onto which the hybrid films (Pt/PAQ/CuHCFe) were electrodeposited by potential cycling. Electrochemical behavior of the modified electrode was well characterized using cyclic voltammetry technique. The hybrid film modified electrode showed improvement in the electrochemical response in aqueous and non aqueous media compared with the polymer film (PAQ) single layer. Moreover a good electrocatalytic activity towards the oxidation of hydroquinone (H2Q) was observed. In addition, the electrode exhibited a distinct advantage of good chemical and mechanical stability. (doi: 10.5562/cca1920
