We carried out an investigation on the influence of several alkylamines, fr
equently present in reactions carried out in microemulsions, on the propert
ies of the water/AOT/isooctane system, The presence of alkylamines has an i
mportant effect on the electrical percolation phenomena. This effect of ami
nes on the electrical percolation of microemulsions of AOT/isooctane/water
can be explained by taking into account the ability of these substrates to
associate with the AOT film in the microemulsion, the basicity of the amine
, and the different solubility of the amine in the three pseudophases Of th
e system. (C) 2000 Academic Press.
