The anion exchange membrane (AEM) with high and stable conductivity is important to the com. application of anion exchange membrane fuel cell. The AEM based on the polymer of quaternized poly(phenylene) oxide (QPPO) with enhanced anion conduction stability has been constructed through the introduction of the ionic liquid (IL) of 1-aminopropyl-3-methylimidazolium bromide (APMIMBr)-modified carbon nanomaterials, such as carbon nanotubes oxide (OCNT) and graphene oxide (GO) nanosheets. The IL-OCNT and IL-GO composites prevented hydroxyl groups from attacking the polymer of QPPO. Thus, QPPO/x(IL-OCNT) and QPPO/x(IL-GO) series membranes possessed enhanced hydroxide conductivity stability in alk. solution Specifically, QPPO/5%(IL-OCNT) and QPPO/5%(IL-GO) membranes exhibited the hydroxide conductivities of 23.0 and 28.5 mS/cm at 80°C. Notably, the hydroxide conductivities could reach 16.3 and 30.2 mS/cm while the prepared membranes were immersed in 2 M KOH solution for 1848 h. Furthermore, the stable hydroxide conductivity was derived from the fine dimension stability and mech. property. The tensile stress values were, resp., 19.4 and 19.8 MPa even if the membranes were immersed in alk. solution In the prepared QPPO/x(IL-OCNT) and QPPO/x(IL-GO) membranes, In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Recommanded Product: 128-08-5).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Recommanded Product: 128-08-5
