Interaction of surfactants with ion-exchange membranes

In the present paper, we have compared the measuring results of the water content and electrotransport properties of the heterogeneous and perfluorinated homogeneous ion-exchange membranes with the variable saturation degree by surface-active counter-ions. Pore-size distribution functions for the heterogeneous membranes are investigated and the specific internal surface area is calculated. The key role of the surfactant-adsorption on the internal and external boundaries of the ion-exchange membranes is revealed. The correlation between percolation phenomena in the perfluorinated membrane with tetrabutylammonium ions and effects of the system transition to overlimiting state is found.
