Annotation:

Lon-exchange membranes, subjected to modification by polyaniline in a new way, were investigated with an atomic force microscope. The obtained images of the surfaces confirm the change in their morphology resulting from the modification. Experimental data on the diffusion constant of the modified membranes were processed in the framework of a charged bilayer membrane, and the absence of asymmetry of diffusion permeability of the modified membrane in the experiment observed is explained.
