Kim, Jun Ha; Vinothkannan, Mohanraj; Kim, Ae Rhan; Yoo, Dong Jin published an article in 2020, the title of the article was Anion exchange membranes obtained from poly(arylene ether sulfone) block copolymers comprising hydrophilic and hydrophobic segments.SDS of cas: 80-07-9 And the article contains the following content:
The anion exchange membrane may have different phys. and chem. properties, electrochem. performance and mech. stability depending upon the monomer structure, hydrophilicity and hydrophobic repeating unit, surface form and degree of substitution of functional groups. In current work, poly(arylene ether sulfone) (PAES) block copolymer was created and used as the main chain. After controlling the amount of NBS, the degree of bromination (DB) was changed in Br-PAES. Following that, quaternized PAES (Q-PAES) was synthesized through quaternization. Q-PAES showed a tendency of enhancing water content, expansion rate, ion exchange capacity (IEC) as the degree of substitution of functional groups increased. However, it was confirmed that tensile strength and dimensional properties of membrane reduced while swelling degree was increased. In addition, phase separation of membrane was identified by at. force microscope (AFM) image, while ionic conductivity is greatly affected by phase separation The Q-PAES membrane demonstrated a reasonable power output of around 64 mW/cm2 while employed as electrolyte in fuel cell operation. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).SDS of cas: 80-07-9
