Features of Thermomechanical Stability of Anionic–Cation Exchange Matrix “Polikon AC” on Viscose Non-Woven Materials

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.

Anion-Exchange Membrane “Polikon A” Based on Polyester Fiber Fabric (Functionalized by Low-Temperature High-Frequency Plasma) with Oxidized Metal Nanoparticles

“…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.…”

“…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.…”

Mathematical Modeling of the Electrophysical Properties of a Layered Nanocomposite Based on Silicon with an Ordered Structure

“…The increased interest of scientists, researchers, and engineers in modern composite materials is based, first of all, on a wide range of their physical and chemical properties in relation to various areas of human activity [1,2]. The prospect of using composite materials is due to many factors, the most important of which are the availability of raw materials [3] and multifunctionality [4].…”
