摘要：

The sorption of solvent molecules and ions in poly(vinylferrocene) films was studied under potential cycling conditions as a function of the electrolyte composition. The results indicate that only the redox behaviour of PVF films but also the film swelling is dependent on the nature and concentration of supporting electrolyte. The study of the break-in process revealed that significant accumulation of the solution species occurs in the neutral films. It was found that the degree of swelling depends also on the conditions of film preparation. Due to the extensive swelling an interplay between the elastic and viscous behaviour may complicate the evaluation of the results obtained by electrochemical quartz crystal microbalance method.
