Nanoscopic conducting polypyrrole powder was prepared in an oil/water microemulsion with FeCl 3 as a dopant. Compared with solution and conventional emulsion polymerizations, a microemulsion polymerization system increases the yield of the resultant polypyrrole. The results of FTIR spectra and therm

We study the static electric conductivity in water-in-oil microemulsion systems both in the droplet phase and in the vicinity of a percolation transition in the non-percolating region. We discuss the mechanisms of conduction in the two regimes. In particular, we interpret the behavior of conductivit
Current-voltage characteristics of water/AOT/isooctane (W/O) mtcroemulsions were studied. The measured current consists of two components: an instantaneously responding part which indicates the degree of connectivtty of the dtspersed aqueous nanodroplets at any gtven temperature and concentratton. a
The dielectric and conductometric spectra of water-in-oil microemulsions below percolation in the frequency range from 1 MHz to 1.8 GHz have been analyzed on the basis of the electrical modulus formalism. In the frequency range investigated, this approach clearly evidences the presence of a particul
