Time domain dielectric spectroscopy of reverse water/acrylamide/Aerosol-OT (AOT)/toluene microemulsions shows
that percolation induced by increasing cosurfactant concentration (increasing cosurfactant chemical potential) obeys
scaling above and below a percolation threshold.This scaling analysis suggests that the observed percolation is close to
static percolation limits.Self-diffusion measurements derived from nuclear magnetic resonance pulsed-gradient spin-echo
experiments reveal an increase in water proton diffusion above the percolation threshold.This increase is assigned to
water transport through fractally chained assemblies of microemulsion droplets.The diffusion of water,cosurfactant,
and surfactant (AOT) below threshold is modeled quantitatively taking into account the chemical partitioning equilibria
between the microemulsion droplets and the toluene continuous pseudophase.Above threshold,the apparent increasing
water and cosurfactant partitioning into the toluene (continuous) pseudophase suggests facilitated transport through
fractal aggregates.A dynamic partitioning model is used to estimate the volume of percolating fractal clusters,and yields
an order parameter for water-in-oil to percolating cluster microstructural transitions.This same order parameter is also
illustrated to derive from self-diffusion data wherein percolation and transformation to sponge phase microstructure are
driven by increases in temperature and in disperse phase volume fraction.For microstructural transitions driven by three
different field variables,chemical potential,temperature,and disperse phase volume fraction,this order parameter shows
that the onset of percolation corresponds to the onset of increasing water proton sell-diffusion,and that the onset of
increasing surfactant self-diffusion corresponds to the formation of bicontinuous microstructures and the onset of
transformation to middle phase microemulsion.© 1997 Elsevier Science B.V.
