On December 8, 2020, Nugraha, Adam F.; Kim, Songmi; Shin, Sung-Hee; Lee, Hyejin; Shin, Dongwon; Bae, Byungchan published an article.Related Products of 80-07-9 The title of the article was Chemically Durable Poly(phenylene-co-arylene ether) Multiblock Copolymer-Based Anion Exchange Membranes with Different Hydrophobic Moieties for Application in Fuel Cells. And the article contained the following:
Quaternized multiblock poly(phenylene-co-arylene ether)s (QPPs) are synthesized from a pre-aminated monomer and a series of chlorine-terminated oligo(arylene-ethers) via a nickel coupling reaction. Their properties are investigated as anion exchange membranes with the goal of obtaining membranes with enhanced performance and durability for alk. membrane fuel cell applications. Three different oligo(arylene ethers) were synthesized and introduced in the hydrophobic block of the polymer backbone to study its effect on the membrane properties. The chloride ion conductivity of the QPP membranes was significantly less dependent on the humidity compared to that of the com. Fumatech membrane due to the well-defined hydrophilic-hydrophobic phase separation, as confirmed by TEM. An accelerated alk. stability test indicated that the QPPs were more stable than the com. Fumatech membrane up to 1700 h. The QPP-6F membrane shows an alk. membrane fuel cell single-cell performance with a maximum power d. of 534 mW cm-2 at 70°C. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9
