Anion exchange membranes (AEMs) with robust alk. stability and high ionic conductivity are imminently required for the promising electrochem. energy conversion devices – fuel cells. Herein, a series of novel crosslinked AEMs with hydrophobic fluorine-based polymer backbones bearing special functional sites and hydrophilic long flexible multi-cation side chains are prepared Morphol. observation and ion transport anal. confirm the existence of distinct microphase separation and efficient ion-conducting channels within the membranes resulting from the inherent chem. structure. A highest ionic conductivity of 136.27 mS cm-1 can be achieved by TQ-PDBA-70% (IEC = 2.16 meq. g-1) at 80°C. Meanwhile, the prepared TQ-PDBA-X AEMs exhibit a desirable swelling ratio (<10%) and excellent mech. properties (tensile stress > 22.8 MPa). It is worth noting that the retained ionic conductivity of the TQ-PDBA-70% AEM is 98.14%, 95.50%, 77.90%, 72.02% and 58.15% after being immersed in 1, 2, 4, 8 and 10 M KOH at 80°C for 1000 h, resp. Chem. structure change of the TQ-PDBA-70% AEM before and after the alk. stability test is negligible, as revealed by FT-IR. Moreover, TQ-PDBA-70% has high ionic exchange capacity (IEC) retention and maintains good mech. properties. A single cell assembled with TQ-PDBA-70% has a maximum power d. of 158.8 mW cm-2 under a c.d. of 360 mA cm-2. These results suggest that this type of structure opens a new strategy for developing high performance AEMs. The experimental part of the paper was very detailed, including the reaction process of 1,6-Dibromohexane(cas: 629-03-8Related Products of 629-03-8)
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.Related Products of 629-03-8
