Crosslinking is a valid approach to enhance the mech. and durability performance of anion exchange membranes (AEMs). Herein, a facile and effective self-crosslinking strategy, with no need for an addnl. crosslinker or a catalyzer, is proposed. A series of tunable self-crosslinking and ion conduction polynorbornene membranes are designed. The 5-norbornene-2-methylene glycidyl ether (NB-MGE) component which affords self-crosslinking enhances dimensional stability, while the flexible 5-norbornene-2-alkoxy-1-hexyl-3-Me imidazolium chloride (NB-O-Im+Cl–) hydrophilic unit contributes high conductivity The crosslinking significantly decreases the water uptake, and water swelling ratio provides excellent solvent-resistance and enhances the thermal and mech. properties. Addnl., crosslinked rPNB-O-Im-x AEMs exhibit desirable alk. stability. Impressively, the rPNB-O-Im-30 (IEC = 1.377) shows a moderate ion conductivity (61.8 m S cm-1, 80°C), with a suppressed water absorption and 88.17% initial OH– conductivity is maintained after treated for 240 h with a 1.0 M NaOH solution at 60°C. Suitably assessed of rPNB-O-Im-30 AEM reveals a 98.4 mW cm-2 peak power d. reached at a c.d. of about 208 mA cm-2. The report offers a facile and effectual preparative technique for preparing dimensional and alk. stable AEMs for fuel cells applications. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Synthetic Route of C6H12BrCl).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Synthetic Route of C6H12BrCl
