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.
