The electrochemical redox processes in methacrylate-based gel electrolytes II. -study on microelectrodes
Original language description
The electrochemical behaviour of ferrocene was studied in different gel polymer electrolytes based on methyl, ethyl and 2-ethoxyethyl methacrylate and compared to the liquid aprotic solution (propylene carbonate). Voltammetric and chronoamperometric measurements on microelectrodes were conducted in order to describe the qualitative as well as quantitative behaviour of ferrocene in different conditions. Heterogeneous electron-transfer rate constants and diffusion coefficients of ferrocene in polymer electrolytes were estimated to be 1.1-7.8 x 10(-3) cm s(-1) and 4-13 x 10(-8) cm(2) s(-1) depending on the electrolyte composition. The influence of the polymer polarity, ferrocene concentration and level of polymer cross-linkage on the kinetics of ferroceneoxidation and its transport was discussed. The electrolytes with poly(2-ethoxyethyl methacrylate) exhibit the highest ionic conductivity (2-4 x 10(-4) S cm(-1)) as well as diffusion coefficient of ferrocene (1.3 x 10(-7) cm(2) s(-1)) in
