Abstract
The thermomechanical stability of the anion–cation exchange matrix “Polikon AC” on viscose nonwoven materials is investigated. In this work, a molecular model of a solvation environment for experimentally obtained “Polikon AC” mosaic membranes is refined. Mosaic membranes on a viscose fiber base were fabricated by the method of polycondensation filling. The temperature dependence of deformation was investigated for dry and wet anion and cation exchange membrane components at a constant tensile load of 1.5 N and a heating rate of 8 °C/min. The effect of moisture content on the deformation of anionite and cationite fragments under a constant external tensile load of 1.5 and 3 N in a temperature range up to 100 °C was studied.

Summary
Accepted: 23 September 2021Today, it is undeniable that the creation of synthetic ion-exchange membranes is possible only at the junction of macromolecular chemistry, quantum chemical calculations, electrochemistry, thermodynamics, ion exchange, colloid chemistry, and modern research methods [1]. The desalination of seawater is becoming one of the mass sources of drinking water and is important for ensuring a sustainable quality of life while meeting high world environmental standards. This includes the treatment of urban and agricultural waste and the treatment of industrial effluents. Membrane technology is recognized as energy efficient, scalable, and clean, with a large prospective expansion of its application to the growing need for implementing more stable industrial processes [3]. The generated data set was processed using software for visualization and analysis of the related data [4], which made it possible to form semantic network cartograms (Figure 1)
