| 中文摘要 | the mass transport dynamics of ferrocene in polyelectrolyte polyethylene glycol lithium perchlorate (peg . liclo4) was studied by using chronoamperometry at a microdisk electrode. chronoamperometry is a powerful method for the study of mass transport in polyelectrolyte, it has many advantages over the conventional methods at a microelectrode and the steady-state method at an ultramicroelectrode. by using this method the apparent diffusion coefficient d-app and concentration c-a of the electroactive species, can be estimated from a single experiment without previous knowledge of either one. we have estimated d-app and c-a of ferrocene in peg . liclo4 polyelectrolyte from 25 degrees c to 75 degrees c. the dependence on the concentration of electroactive species was observed. the diffusion coefficients decrease with increasing ferrocene concentration and decreasing temperature. the mass transport mechanism is explained, by using a free volume model. |
