The N1-substituted (Me, iso-Pr, Bu, benzyl or dodecyl) 2-methylimidazolium functionalized polynorbornene (rPNB-RMIm-30) AEMs are prepared and the effects of substituents are studied. The N1-Bu or isopropyl-substituted 2-methylimidzolium (rPNB-BuMIm-30 or rPNB-iPrMIm-30) anion exchange membrane (AEM) reveals much better alk. durability than that of Me, benzyl and dodecyl-substituted 2-methylimidazolium-based AEMs, reflected by the almost unaltered FT-IR spectra and TGA curves after being subjected to 1 M NaOH for 720 h at 60°C, with a conductivity degradation of 17% and 14% resp. Furthermore, a highest hydroxide conductivity (51.5 mS cm-1, 80°C) is achieved of the rPNB-BuMIm-30 AEM, attributing to its well-defined phase-separated structure, as evidenced by results of at. force microscope (AFM) and X-ray scattering (SAXS). Membrane electrode assembly (MEA) with rPNB-BuMIm-30 AEM exhibits a peak power d. of 205 mWcm-2 at 60°C. This study paves the way of N1-Substituented 2-methylimidazolium-based AEM for fuel cells practical application. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Related Products of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Related Products of 6294-17-3
