Anion exchange membranes (AEMs) are widely studied as an important component of fuel cells. In this paper, series self-crosslinking AEMs are obtained by copolymerization of the prepared bis-imidazolium functionalized ionic liquids The block copolymer shows excellent thermal stability with a decomposition temperature (Td) of 300°C. And the mech. properties of AEMs in OH- are significantly improved due to the crosslinking of epoxy groups. The transmission electron microscopy (TEM) test results show a good microscopic phase separation structure and form ion channels in the membranes, which is benefited to ions conductivity The OH- conductivity of AEMs is measured as above 2410-3Scm-1 and 9510-3Scm-1 at 30°C and 80°C, resp. In addition, the AEMs also exhibits excellent swelling performance, the highest is only 20.86% at 80°C. And the conductivity of all AEMs remained above 90% after being immersed in 1MNaOH aqueous at 60°C for 250 h. The peak power d. of the AEMs reaches 207.95 mW cm-2 at c.d. of 403 mA cm-2. In addition to this study using 1,6-Dibromohexane, there are many other studies that have used 1,6-Dibromohexane(cas: 629-03-8Product Details of 629-03-8) was used in this study.
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of solvent processable and conductive polyfluorene ionomers for alkaline fuel cell applications; synthesis of cross-linkable regioregular poly(3-(5-hexenyl)thiophene) (P3HNT) for stabilizing the film morphology in polymer photovoltaic cells.Product Details of 629-03-8
