摘要：

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. (C) 2004 Elsevier B.V.
