Quaternized poly (styrene-co-vinylbenzyl chloride) anion exchange membranes for alkaline water electrolysers
2015, Journal of Power SourcesCitation Excerpt :AAEMs are OH− ion conductive solid polymer electrolyte membranes which mostly contain quaternary ammonium (QA) groups grafted into the polymer chains. Several quaternary ammonium functionalized polymers such as poly (arylene ether sulfone), poly (phenylene oxide), poly (ether sulfone ketone) and poly (vinyl alcohol) have been developed and used as AAEM materials [17–20]. A key challenge in developing AAEM is to enhance the stability of cationic groups attached to the polymeric backbone.
Electrodialytic properties of aromatic and aliphatic type hydrocarbon-based anion-exchange membranes with various anion-exchange groups
2014, PolymerCitation Excerpt :The transport number of an IEM depends on the ratio of the charge density to the concentration of solution in contact with the membrane surface [31]. The charge density is defined as the division of the ion-exchange capacity by the water content of an AEM [32,33]. Table 2 shows that the transport number of both the aromatic and the aliphatic AEMs reacted with TMA increases with increasing CLC.
Charge mosaic membranes with semi-interpenetrating network structures prepared from a polymer blend of poly(vinyl alcohol) and polyelectrolytes
2013, Journal of Membrane ScienceCitation Excerpt :In order to examine the effect of charged groups on ionic transport through the membranes, a non-charged PVA membrane, PVA-1, was prepared by casting an aqueous solution of PVA on a plastic plate, drying the membrane obtained, and then annealing it under the same conditions as mentioned above. The membrane potential, Δϕ, of PBCM membranes was measured using an acrylic plastic cell comprising two parts separated by a sample membrane, as shown elsewhere [31]. One chamber of the cell was filled with 0.01 mol dm−3 KCl solution, while the other chamber was filled with 0.05 mol dm−3 KCl solution.
Characterization of cation-exchange membranes prepared from poly(vinyl alcohol) and poly(vinyl alcohol-b-styrene sulfonic acid)
2012, International Journal of Hydrogen EnergyCitation Excerpt :Fig. 2 shows the chemical cross-linking mechanism of PVA and GA. The electrical resistance of the membranes was measured by using a hand-made acrylic plastic cell composed of two parts separated by a membrane, as described elsewhere [32], with an LCR meter operated at 10 KHz AC (A&D Corp. Ltd.

2011, Journal of Membrane ScienceAnion exchange membranes for alkaline fuel cells: A review
2011, Journal of Membrane ScienceCitation Excerpt :The ion exchange capacity obtained was 1.1 × 10−3 eq g−1 [154]. Also, PVA was blended with poly(allyl amine) and cross-linked with glutaraldehyde [155]. Recently, AEMs based on cross-linked PVA-poly(acrylonitrile-co-2-dimethylamino ethylmethacrylate) were developed [156].
