Porous structure of ion exchange membranes investigated by various techniques

This review concerns the chemical structure and synthesis of perfluorinated sulfocationite membranes, among which Nafion, MF-4SC, Flemion, Aciplex-S, and Dow membranes are the most well-known representatives. Special attention is given to main mechanisms controlling the formation of microstructure and its relationship with transport processes and selectivity levels of membranes. Key approaches to the modification of ion-exchange materials, above all involving the synthesis of hybrid membranes containing nanoparticles of inorganic compounds, are described. It is noted that increases in the conductivity and selectivity levels of hybrid membranes are primarily related to changes in structure of pores and channels and in the distribution of the concentration of carriers in them. Some examples of the practical use of perfluorinated membranes in modern technologies are highlighted.

Perfluorinated ion-exchange membranes

In this review, modern notions on the structure and properties of one of the most in-demand classes of nanomaterials—ion-exchange membranes—are generalized. Data are presented on their transport properties, on their use in electrodialysis and in alternative power engineering, on the methods of their modification that lead to changing the conducting and selective properties of membranes, and on certain aspects of their use in modern technologies.
