摘要：

Precise diffusion coefficient measurements have been performed using chronoamperometry in highly concentrated ionically conducting polymer solutions made with DMF as the solvant (solid polymer gels). The D variation with the temperature lets appear a transition temperature which is characteristic of the system. Interpretation of the results in terms of a free volume law is proposed and agrees well with the experimental D variation and allows to determine some of the parameters for a given gel.
