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.

Experimental Uncertainty

SrI2 ions at 0.8 M in water are present with a structure that can scatter neutrons, and, within experimental uncertainty, the structure does not change between 10 °C and 90 °C, showing an organization that must be reconciled with ionic transport.

The proton magnetic resonance spectra of cation-exchange resins of crosslinkage X1 to X16 in the H+, Li+, Na+, K +, Rb+, Cs+, and NH4+ forms have been recorded and the values of the molal chemical shift, δM+0, are found to be −0.321, −0.005, 0.041, 0.031, 0.028, 0.015, and 0.00 (assumed) p.p.m./mole, respectively, for the cations. These values are very nearly equal to those observed in corresponding aqueous solutions, indicating that ion–solvent interactions are similar in both the resin matrix and the aqueous solution. The temperature dependence of the chemical shift shows the same trend. The effective hydration numbers calculated from the temperature dependence are 2.0 (4.81 m) for the H+ form, 4.8 (3.25 m) and 3.6 (5.26 m) for the Na+ form, 4.4 (3.9 m) for the K+ form, and 2.4 (6.18 m) for the Cs+ form. The ions in the resin phase behave as solutions of strong electrolyte, which is consistent with the polyelectrolyte gel model for the ion-exchange resin.
