Percolation in fluorinated microemulsions: A dielectric study
Steinkopff eBooks2007pp. 182–185
Abstract
This work deals with the dielectric investigation of fluorinated water-in-oil microemulsions with perfluoropolyether (PFPE) compounds. The microemulsion ohmic conductivity and dielectric constant at different temperatures and frequencies have been studied at water to surfactant molar ratio W/S = 11 for monophasic samples having volume fractions of the dispersed phase, φ, in the range 0.2 to 0.6 The study as a function of temperature in the interval −10o to 40°C showed a percolation phenomenon (Phys Rev E (1994) 50:1313). The analysis in terms of scaling laws and the calculation of the scaling exponents indicated that the percolation process is mainly dynamic. Preliminary results are here presented of the study as a function of frequency.
