Abstract

Monte Carlo calculations were carried out to simulate ion diffusion through polymer matrices. A dynamic bond percolation (DBP) model was employed that includes local harmonic motion of covalently bound anions in polyelectrolyte systems. The temperature dependence of cation diffusion was investigated in polyelectrolytes and polymer-salt complexes for 0-100 °C. Systems in which the rate of polymer reorganization is independent of temperature display Arrhenius behavior both above and below the T_g of 35 °C. Systems in which the temperature is coupled to the rate of polymer reorganization display VTF behavior above the T_g and near Arrhenius behavior below the T_g. In all cases, the temperature is coupled to the rate of successful ion jumps. Temperature and T_g seem to have no effect on the ion density at which the cation conductivity reaches a maximum.
