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

Abstract

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.

Plasma Technology Applications in Proton Exchange Membrane Fuel Cell Systems

“…[86] The PBI membrane treated with Ar/O 2 plasma by Gao et al exhibits high oxygen content and phosphoric acid retention, demonstrating excellent proton conductivity without sacrificing mechanical strength [87] (Figure 13). Terin et al [88] employed a plasma treatment technique to produce anion exchange membranes on polyester fiber fabric. In comparison to untreated membranes, those prepared with plasma exhibited a 20 % increase in ion-exchange capacity.…”

“…Shcherbakov et al [ 12 ] investigated the impact of microwave modification on both the structure and imperfection degree of multi-walled carbon nanotubes (MWCNTs). In another study, the effect of the low-temperature argon plasma treatment of fabrics based on polyester fibers, in order to subsequently control polycondensation synthesis of anion-exchange composite heterogeneous membranes, has been presented by Terin et al [ 13 ]. Cyras et al [ 14 ] studied the effect of chemical treatment on the mechanical properties of starch-based blends reinforced with sisal fiber.…”

A Commemorative Special Issue in Honor of Professor Victor Nikonenko

“…In their article, Denis Terin et al [ 10 ] discuss the creation of reinforced ion exchange polymeric materials based on thermosetting matrices and high-temperature fibers with increased mechanical strength and chemical resistance. An original method for obtaining heterogeneous anion exchange composite membranes with the low-temperature ion plasma pretreatment of a polyester fibrous system is proposed.…”
