The electrochemical redox process in PMMA gel electrolytes-behaviour of transition metal complexes

Original language description

Electrochemical properties of polymer gel electrolytes based on polymethylmethacrylate (PMMA) were studied by cyclic voltammetry and impedance spectroscopy using new solid-state PMMA-Cd-Cd2+ reference electrode. The suitable potential window of the PC-PMMA system was estimated from -0.2 to + 1.5 V versus Cd-Cd2+. New polymer gels containing ferrocene-ferricinium (Fc-Fc(+)) couple and other transition metal complexes were prepared by the direct polymerisation of methylmethacrylate (MMA) monomer and the solution of metal complex and supporting electrolyte in anhydrous aprotic solvent-propylene carbonate (PC). The half-wave potentials and apparent diffusion coefficients of used complexes and their dependence on the composition of the system (liquid or gel) were estimated. The results show that the PC-PMMA gel electrolyte can be described as a system of embedded solvent in the polymer network of PMMA without present monomer.

Elektrochemické redoxní procesy v PMMA gelových elektrolytech ? chování komplexů přechodných kovů

Czech description

Byla studována kinetika elektrochemických redoxních reakcí ferrocenu a komplexů kobaltu v prostředí polymerních gelových elektrolytů na bázi PMMA - propylenkarbonát. U komplexů byly v prostředí kapalného a gelového elektrolytu stanoveny difúzní koeficienty.
