Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Partially fluorinated, multication cross-linked poly(arylene piperidinium) membranes with improved conductivity and reduced swelling for fuel cell application.Name: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine.
As an important component in alk. membrane fuel cells, anion exchange membrane (AEM) often suffers from the tradeoff between ionic conductivity and chem./dimensional stability. We herein report a partially fluorinated poly(arylene piperidinium) AEM with multication cross-links, which was synthesized by copolymerizing 1,1,1-trifluoroacetone, N-methyl-4-piperidone, biphenyl, and subsequent crosslinking with N1, N6-bis(6-bromohexyl)-N1, N1, N6, N6-tetramethylhexane-1,6-diammonium bromide. The resultant AEM exhibited an excellent OH- conductivity of 148.7 mS cm-1 at 80 °C (IEC = 2.9 mmol g-1) due to the multication structure, which may promote microphase separation to produce wide ion-conducting channels. Compared with those without partial fluorination, the fluorinated AEM showed lower swelling ratio (33% vs. 58% at 80 °C). The ionic conductivity of the AEM remained by 85% after it was treated 1700 h in 1 M NaOH at 80 °C. In addition, the H2/O2 fuel cell assembled with the AEM yielded a peak power d. of 208 mW cm-2 at 60 °C. Our work successfully demonstrates the synergistic effect of partially fluorinated backbone and multication cross-linked structure to inhibit membrane swelling while keeping high conductivity; it is beneficial for better balancing AEM conductivity and robustness. Partially fluorinated poly(arylene piperidinium) AEM with multication cross-links. The fabricated membrane showed higher conductivity and much lower swelling compared with its non-fluorinated counterpart. [graphic not available: see fulltext]
