Abstract: Methods of directional variation of properties of perfluorinated sulfo cation-exchange membranes were proposed based on the use of the effect of ‘memory’ to changes in their structure under the influence of external factors (heat treatment at various humidity or mechanical effect). The relationship between water uptake, transport properties of MF-4SC membranes, and sensitivity of Donnan potential (DP) sensors to the determined organic cations and interferent hydronium ions was established. Lowering sensitivity of DP-sensors to the interferent hydronium ions at a decrease in diffusion permeability and increase in conductivity of the membranes was reached.
