ABSTRACT:
The invention relates to microemulsions of the water-in-oil type (w/o) capable of effecting ionic electric transfer and material interphase transfer, wherein the oily phase consists of a perfluoropolyether having perfluoroalkyl end groups or functional end groups of the hydrophilic type. The microemulsions are obtained using perfluorinated surfactants, in particular having a perfluoroalkylpolyethereal structure, and/or an alcohol as a co-surfactant.
