“…We fabricated laboratory pilot-scale batches of membranes “Polikon A” (letter “A” denotes an AEM, and the term “Polikon” corresponds to the original technological method of membrane production fabricated by the authors [ 34 , 35 , 36 , 37 , 38 , 39 ]). Membranes were formed using polyester fiber-based fabrics treated and not treated with plasma.…”

“…The technological process consisted of the pretreatment of the raw materials, the preparation of monomerization composites (on the basis of polyethylene polyamines and epichlorohydrins), and their application on a fibrous base; then, the synthesis and curing process was carried out, thereby forming a spatial network of polymer matrices on the surface and in the volume of the system [ 34 , 35 ].…”

“…Comprehensive studies of the influence of the method of manufacturing a fibrous base on the properties of ion-exchange membranes have been carried out by the authors of articles [ 34 , 35 , 36 , 37 , 38 , 39 ]. In these studies, polyester fibers pretreated with low-temperature high-frequency plasma were proposed as the fibrous substrate of the membranes.…”

An experimental laboratory set of samples of composite heterogeneous anion-exchange membranes was obtained by us for the development of our original method of polycondensation filling. Anion-exchange membranes were prepared on plasma-treated and non-plasma-treated polyester fiber fabrics. The fabric was treated with low-temperature argon plasma at a power of 400 W for 10 min at a pressure of 5 × 10−5 mbar. On the surface and bulk of the polyester fiber, a polyfunctional anionite of mixed basicity was synthesized and formed. The anion-exchange membrane contained secondary and tertiary amino groups and quaternary ammonium groups, which were obtained from polyethylene polyamines and epichlorohydrins. At the stage of the chemical synthesis of the anion matrix, oxidized nanoparticles (~1.5 wt.%) of silicon, nickel, and iron were added to the monomerization composition. The use of ion-plasma processing of fibers in combination with the introduction of oxidized nanoparticles at the synthesis stage makes it possible to influence the speed and depth of the synthesis and curing processes; this changes the formation of the surface morphology and the internal structure of the ion-exchange polymer matrix, as well as the hydrophobic/hydrophilic balance and—as a result—the different operational characteristics of anion-exchange membranes.

In this paper, the objects of study are heterogeneous cation-exchange materials Polykon, obtained on a fibrous system that has undergone preliminary preparation by low-temperature high-frequency argon plasma at power of 400 W for 10 min at a pressure of 5 × 10–5 mbar. As a fibrous system, a fabric made of novolac phenol-formaldehyde fibers—Kynol was used. The surface of the fibrous system before and after plasma treatment using scanning electron microscopy was studied. The hydrophilic/hydrophobic balance was examined on the surface of a fabric made of phenol-formaldehyde novolac fibers—Kynol (before and after treatment) and on heterogeneous cation-exchange materials Polykon, it was noted that on the treated FS and materials, a decrease in the rate of change in the work of wetting was observed. The paper presents the characteristic IR spectra of the samples under study, as well as a thermogravimetric analysis of heterogeneous cation-exchange materials Polykon (obtained on fibers before and after plasma treatment). The presented results indicate a significant effect of low-temperature ion-plasma treatment on the structure of novolac phenol-formaldehyde fibers and Polykon materials based on them.
