Case Study
Polyquaternium-22 for the Preparation of High-Performance Anion-Exchange Membranes in Electrodialysis
Butylskii, Dmitrii Y., et al. Membranes 12.11 (2022): 1065.
Polyquaternium-22 (PQ-22) was employed as a surface modifier to enhance the electrochemical performance of commercial anion-exchange membranes (AEMs) in electrodialysis applications. PQ-22, a copolymer of diallyldimethylammonium chloride (DADMAC) and acrylic acid, contains a high density of quaternary ammonium groups, which effectively replace weakly basic amino groups on the membrane surface and interact with fixed positively charged sites via carboxyl functionalities.
Modification of MA-41P and Ralex AHM-PES membranes was achieved by soaking pristine membranes in an aqueous 2.5 wt% PQ-22 solution for 8 hours at ambient conditions, followed by thorough rinsing to remove unbound polymer. The process maintained the baseline structural and physical parameters of the membranes while enhancing surface charge density.
Electrochemical analysis revealed that PQ-22 modification increased the limiting current density by over 1.5-fold and reduced the plateau length by 2.5-fold, indicating intensified electroconvective mixing and decreased water-splitting rates at the membrane surface. Direct visualization of vortex structures confirmed the enhancement of electroconvection. These effects contributed to significantly mitigated scaling during electrodialysis, demonstrating improved operational stability and ion transport efficiency.
The study illustrates that PQ-22 functions as an effective polymeric modifier for the preparation of high-performance AEMs, offering a facile approach to improve electrochemical behavior and surface anti-scaling properties. This approach highlights the potential of quaternary ammonium-based polymers in industrial membrane modification strategies, particularly for advanced electrodialysis and water treatment processes.
