Je. Companik et Sa. Bidstrup, THE VISCOSITY AND ION CONDUCTIVITY OF POLYDIMETHYLSILOXANE SYSTEMS .2. ION CONCENTRATION EFFECTS, Polymer, 35(22), 1994, pp. 4834-4841
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.
