Abstract
A homologous series of polydimethylsiloxane (PDMS) oils was doped with varying amounts of PDMS salts of three different univalent cations (s odium, tetramethylammonium and tetrapropylammonium). The zero-shear-ra te viscosity and ion conductivity of each sample were measured over th e temperature range -50-degrees-C < T < 60-degrees-C. Free volume and Arrhenius type viscosity and ion conductivity models were successfully applied to these data. The effects of mobile ion concentration on the values of the best-fit model parameters were explored.
