On May 14, 2021, Yang, Rui; Dai, Pei; Zhang, Shu; Xu, Ri-Wei; Hong, Song; Lin, Wen-Feng; Wu, Yi-Xian published an article.Product Details of 5036-48-6 The title of the article was In-situ synthesis of cross-linked imidazolium functionalized Poly(styrene-b-isobutylene-b-styrene) for anion exchange membranes. And the article contained the following:
The crosslinked imidazolium functionalized anion-exchange membranes is in-situ prepared via reaction of chloromethylated poly(styrene-b-isobutylene-b-styrene) with 1,1′-(1,6-hexanediyl)bisimidazole and N-methylimidazole. The composite membranes of cross-linked imidazolium poly(styrene-b-isobutylene-b-styrene) with a small amount of modified graphene oxide grafted with octadecyl and Pr Ph imidazolium could be further prepared These membranes exhibit significantly high chem. stability and ionic conductivity (σ), marked by low methanol permeability, together with improved dynamic mech. properties. The ionic conductivity of crosslinked imidazolium poly(styrene-b-isobutylene-b-styrene) reaches 2.09 x 10-2 S cm-1 at 80°C by introduction of 0.5 wt% loading of modified graphene oxide. This membrane also behaves an excellent chem. stability and σ can remain ca. 82% of the original value after immerged in strong alk. medium (2 M NaOH) at 60°C for 500 h, which is almost the same as that (ca. 82%) of com. Nafion 115 in acid medium (2 M H2SO4) at 60°C for 500 h. The cross-linked imidazolium poly(styrene-b-isobutylene-b-styrene) is characterized as a promising anion exchange membrane materials in fuel cell for its high ionic conductivity, chem. stability and low methanol permeability. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Product Details of 5036-48-6
