Kulasekaran, Poonkuzhali; Maria Mahimai, Berlina; Deivanayagam, Paradesi published an article in 2020, the title of the article was Novel cross-linked poly(vinyl alcohol)-based electrolyte membranes for fuel cell applications.Electric Literature of 80-07-9 And the article contains the following content:
Herein, a new series of polymer electrolyte membranes was prepared by chem. cross-linked poly(vinyl alc.) (PVA) and sulfonated poly(ether sulfone) (SPES). A typical polymerization reaction was conducted using three different monomers i.e. bisphenol A, phenolphthalein, and 4,4′-dichlorodiphenyl sulfone. The SPES polymer was obtained by the post-sulfonation technique using chlorosulfonic acid as a sulfonating agent. The resultant SPES polymer at different concentrations was blended with cross-linked poly(vinyl alc.). Structural anal. of the samples was conducted by FTIR, SEM, and XRD. Among the prepared PEM materials, PVA-SPES-20 blend membranes exhibited higher ion-exchange capacity and % water uptake values than those of the other membranes. In addition, the PVA-SPES-20 membrane exhibits the proton conductivity of 0.0367 S cm-1 at 30°C, whereas pristine PVA shows the proton conductivity of 0.0259 S cm-1. The overall exptl. results revealed that the PVA-SPES blend membranes are promising candidates for fuel cell applications. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Electric Literature of 80-07-9
