The article was titled 《Anion Exchange Membranes Synthesized by Acetalization of Poly(vinyl alcohol) for Fuel Cells》, and you may find the article in ACS Applied Energy Materials.Application In Synthesis of 4-Cyanobenzyl bromide The information in the text is summarized as follows:
High-performance anion exchange membranes (AEMs) are the bottleneck of the commercialization of alk. AEM fuel cells. Various methods have been developed to prepare AEMs with high ionic conductivity, excellent mech. properties, and alk. stability. Among them, modification of various com. polymers is a facile and effective way. To broaden the category of the com. polymer-based AEMs, herein, a series of AEMs based on poly(vinyl alc.) were prepared by acetalization. The PVA-FBMPx-TPAz membrane achieved OH- conductivity up to 200.4 mS cm-1 at 80°C with appropriate water uptake and a low swelling ratio. Moreover, a high peak power d. of 982 mW cm-2 was obtained in a H2/O2 fuel cell test. The experimental process involved the reaction of 4-Cyanobenzyl bromide(cas: 17201-43-3Application In Synthesis of 4-Cyanobenzyl bromide)
4-Cyanobenzyl bromide(cas: 17201-43-3) is used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile. It is also useful in the preparation of 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile by reaction with 2H-tetrazole in the presence of potassium hydroxide.Application In Synthesis of 4-Cyanobenzyl bromide
