    摘要: The invention relates to crystallised, catanionic membranes in organised solid bilayer form, comprising laterally-alternating anionic surfactants (TA) with H+ counter ions and cationic surfactants (TC) with OH- counter ions which are co-crystallised with a mole fraction QTA/(QTA + QTC) greater than 0.5. According to the invention, the membrane forms a surface which is flat, at least locally, and the bilayer is stabilised by at least one polymer which is neutral and hydrophobic or which has an opposite overall electric charge to the effective charge of the catanionic membrane, said polymer being absorbed on the surface. The invention also relates to a method of preparing the membranes, the uses thereof, for example, as a medicament for the vectorisation of active species or for the retention of volatile molecules.
