FIELD: chemistry.
SUBSTANCE: invention relates to membranes made from high-molecular weight polymer compounds, and can be used in electrochemical devices, in hydrogen-oxygen or methanol fuel cells, as well as in sensors. The membrane has a perfluorinated sulphocationite ion-exchange matrix and a polyaniline layer made in form of a barrier layer containing inclusions of polyaniline particles with diametre 0.3-2.3 mcm, where the barrier layer is formed by diffusion of a protonated aniline solution through the perfluorinated sulphocationite ion-exchange membrane first, followed by aqueous solution of ammonium persulphate.
EFFECT: membrane enables intensification electrodialysis and electrolysis processes.
